RENO, Nev. — Transfinder took home best hardware, software and safety technology awards for the second consecutive year and RIDE won best green technology for the third year in a row, as judged by STN EXPO West attendees during the trade show held July 14 and 15.
The 153 attendees who cast votes in the fourth annual STN EXPO Innovation Choice Awards represented a rise in participation from last year’s 125 votes. Exhibitor and guest votes were not counted. Eligible voters represented school districts, state or federal organizations, Head Start agencies, and school bus contractors.
To be eligible for an entry, participating trade show vendors had to introduce a new, market-ready product between January 2024 and July 2025. STN EXPO attendees voted by scanning a QR code at participating company booths.
The Schenectady, New York, company received 114 votes for Best Safety Technology, 123 votes for Best Hardware and 121 votes for Best Software. It was the fourth year in a row that Transfinder won the Best Software category, the third consecutive year winning Best Hardware, and the second year it took all three categories.

Transfinder entered the three products in all three categories.
Stopfinder Digital Card ID turns a student’s Android or IOS cellphone into their ID card. “This advancement eliminates the need for substituting RFID cards and/or replacing lost costs. This technology augments Transfinder’s parent app Stopfinder, providing parents peace of mind that their child made the bus and tracking the bus’s location,” Transfinder stated in its nomination.
Meanwhile, Transfinder Enterprise includes everything from route visibility to attendance routing, posts to student lookup. Transfinder’s Wayfinder ETA dashboard and real-time capability can now be shared with school building personnel and other stakeholders in Viewfinder. This capability enhances communication. Additionally, using the driver app, Wayfinder, the most efficient route based on student riders can be generated.
“For example, a late bus can have different students riding different days depending on the activities they participate in,” Transfinder stated. “When students scan their ID cards as they get on the late bus, for example, the safest and most efficient route is created for the driver.”
Users can post on any record type, such as student, trip or vehicle to facilitate a conversation around that record. The information is then accessible across all Transfinder solutions.
Transfinder said its map incidents solution tackles a growing concern of students crossing by adding a functionality in Routefinder PLUS to “view where students not just cross the street to get on the bus but what streets they cross on their way to the bus. With PLUS, users can embed trip and street data and logic into their maps and trips, making it easier for routers to design safer trips.”
Transfinder noted, adding the data is then viewed on Wayfinder.
Meanwhile, BYD electric school bus spinoff RIDE was unopposed last month in the green technology category. The manufacturer was attendees’ choice for the third consecutive year, this time for its blade battery (below). The manufacturer won the same category last year for its Type C “Creator” and in 2023 for its Type A “Achiever.” The lithium iron phosphate blade battery features a direct cell-to-pack design, utilizing thin “blade-like” cells that eliminate the need for conventional modules.
BYD says its Blade LFP battery in RIDE electric school buses virtually eliminates thermal events, as it passed nail penetration tests, was crushed and bent, and survived being heated in a furnace to 300°C and overcharged by 260 percent.
In another galaxy not that long ago, conversations about contracting school transportation focused solely on the yellow school bus. Not anymore. Today’s discussions, while still centering on school buses, have evolved to include the growth of alternative vehicles such as vans, sedans and SUVs.
Many of these are operated by third-party companies with no previous school bus experience. Traditional school bus contractors also now offer this form of transportation, and that has led the industry to do something that is even more historic. As previously reported, the National Congress on School Transportation in May for the first time approved non-school bus recommendations. This month, I talk with the recent alternative transportation writing committee chair, Tyler Bryan.
He is the education associate for the Delaware Department of Education and de facto state director of student transportation. Bryan is also the president-elect for the National Association of State Directors of Pupil Transportation Services, which organizes NCST.
He told me that this topic has been of great interest to him because Delaware, like all states, is grappling with alternative transportation for schoolchildren and how to provide training and oversight. A couple of states have strong laws or regulations, such as California’s inclusion of mandatory pre-employment drug and alcohol testing among the provisions that go into effect this month. But most states do not. Hence, the writing committee was formed at the behest of my good friend and renowned expert in transporting students with disabilities and preschoolers, Linda Bluth, TSD Conference tenured faculty emeritus and long-time magazine contributor.
The main issues discussed at NCST were driver credentialing, vehicle inspection and student behavior management, as the intent of the recommendations is to more align vans and the like with what is required to operate a school bus. These are much needed aspects of alternative transportation and reasons why recommendations needed to be made in the national school transportation specifications and procedures.
In the meantime, one of the vital aspects of alternative transportation that had not been addressed, at least to the liking of certified child passenger safety technicians I have spoken with, is the issue of child safety restraint systems on these alternative transportation vehicles. The NHTSA-sponsored, eight-hour, hands-on Child Passenger Safety on School Buses seminar that is presented again at STN EXPO West in Reno, Nevada, this month and returns to the TSD conference in Frisco, Texas, in November provides everything a student transporter or a child passenger safety technician needs to know about the differences with CSRS in school buses, compared to other vehicles.
The training also demonstrates how to properly and safely secure students in a variety of CSRSs, whether those are traditional rear- or forward-facing car seats for infants and toddlers, the various safety vests and harnesses that students with disabilities might need, or proper securement and support in wheelchairs.
CPSTs I’ve spoken with were at first dismayed that initial industry conversations on alternative transportation lacked focus on CSRS. In the run up to NCST, a NASDPTS paper on alternative transportation did not mention the need for training alternative transportation providers on correct CSRS usage (Indiana is the only state that requires CSRS for preschool children riding in school buses.) Those same CPSTs expressed relief when CSRS training did make it into the NCST proposal in Des Moines, Iowa, where state delegates approved it.
That was a win for the industry. It gives the guidance that alternative transportation companies as well as school districts need when increasingly transporting students with disabilities, out-of-district students, and preschoolers in non-school bus vehicles. Already we have seen proactive measures taken by providers when it comes to managing student behavior. EverDriven announced earlier this year it is requiring video cameras in all vehicles. Ostensibly in response to the CSRS inclusion in the national specifications, HopSkipDrive last month said it was offering new rider assistants and a “car seat program” in addition to wheelchair-accessible vehicles.
The new industry recommendations that give best-practice guidance on alternative transportation could be a defining moment in the industry’s evolution.You can bookmark that, literally. The updated National School Transportation Specifications and Procedures manual is expected to be available later this summer.

Cybertruck’s air suspension failed dramatically after sitting parked for 12 hours.
Shock and spring pushed through the frame, causing significant structural damage.
Tesla denies warranty coverage, attributing damage to an outside influence.
Air suspension systems offer a unique advantage in modern vehicles, letting drivers adjust ride height on the fly. This makes them especially useful for off-roaders and pickup trucks, where flexibility and ground clearance are key. The Tesla Cybertruck is one of many vehicles to come standard with air suspension, but according to one owner, his truck’s suspension failed dramatically, and with no clear explanation.
Writing on the Tesla Owners Online forum, a member living in Texas says he was at home when he heard a low “shotgun-like bang” from his Foundation Series Cybertruck parked outside. He looked and noticed “smoke or dust” rising from the Tesla’s bed in his driveway.
Most people who hear a bang from an EV may expect the battery to have spontaneously caught on fire, but that’s not what happened here, or at least according to the owner.
A Sudden Collapse
Following the noise, the right side of the Cybertruck immediately began to sag after the bang. The EV was towed to the nearest Tesla service center in Houston. A technician found that one of the shocks and springs had pushed itself upward and damaged part of the Tesla’s frame.
Despite the unusual nature of the failure, Tesla declined to cover the damage under warranty. According to the service center, the failure was the result of an “outside influence.” They also requested $250 from the owner to release the vehicle in its current condition.
The owner has suggested that the extreme Texas temperatures could have caused the air suspension to blow, noting that the truck hadn’t been driven for over 12 hours when the suspension failed in spectacular fashion.
External Damage, or a Design Flaw?
Not everyone on the forum agrees with the temperature theory. One user suggested that, for the air suspension to fail as described, the casing would likely have had to suffer prior damage, possibly from an off-road excursion. The owner admits to driving his Cybertruck off-road, and it’s certainly possible the suspension could have been damaged without him noticing.
Regardless of what caused the damage, no vehicle should suffer catastrophic suspension failure like this, unless it’s driven off a cliff or something like that. While air suspension systems can occasionally run into issues, a spontaneous failure that impacts the frame raises questions, either about unseen damage, the system’s durability, or both.
Could extreme heat have triggered the failure, or did off-road use quietly weaken the suspension until it finally gave way? The cause remains unclear, but it’s certainly not the kind of bang any EV owner wants to hear.
Hyundai is recalling a number of 2025 Ioniq 5 EVs in America due to a fire risk.
The crossovers might have a loose connection that could cause a short circuit.
Only 10 examples of the EV are believed to need their bus bar bolts tightened.
Electric vehicles don’t drive around with half a bathtub worth of flammable liquid slung beneath the rear seat, but it seems they’re even more likely to present a fire risk. The latest automaker to issue a fire-related recall is Hyundai, which is telling some of its EV owners not to park near other cars or buildings until they’ve had some important repair work done to their cars.
The advice – which is easier said than done for people who live anywhere near civilization – applies only to a small number of owners of MY25 Ioniq 5s. Hyundai estimates 10 of the EVs are equipped with batteries whose bus bars weren’t correctly tightened, leading to a risk of a short circuit which could in turn cause a fire.
What Went Wrong
A busbar is a metal strip, usually made from copper or aluminum, that connects the individual cells that make up a battery pack. A neat description from Ennvoi says the battery is the heart of an EV and the busbars are the blood vessels that send electrical current through the car’s various systems.
Hyundai believes a torque tool controller belonging to the Battery System Assembly (BSA) supplier failed, resulting in some bus bars being insufficiently tightened. The error was discovered a routine inspection of battery packs and an audit revealed some of those dodgy batteries has already made their way into delivered cars.
Although no accidents or fires have yet been reported, Hyundai cautions that over time the bus bar retaining bolts could work loose and cause an electrical arcing inside the battery pack. It could also trigger a voltage sensing error that would send the EV into limp mode.
What Affected Owners Should Do
Those 10 rogue Ioniq 5s will need to head back to a dealership to have their bus bar bolts tightened. Hyundai says owners can continue driving until they get the fix, but recommends they think carefully about where they park between now and when they get the all-clear.
The Beachman ’64 tops out at 45 mph and offers up to 70 miles range.
It blends vintage Café Racer looks with a modern electric powertrain.
The electric two-wheeler can charge up to 80 percent in three hours.
Most e-bikes look a little futuristic, but what if you want to ride around on a two-wheeler that looks more like a classic Café Racer, but without spewing harmful toxins into the atmosphere? Well, a company by the name of Beachman has the answer with its new ’64 e-bike, combining modern powertrain technologies with retro looks inspired by some classic motorcycles. By warned, however, this thing isn’t cheap.
At first glance, the Beachman ’64 may look like a motorbike, but practically, it’s more similar to an electric bicycle. For starters, it’s only powered by a small 2.88 kWh lithium battery. Secondly, it tops out at 45 mph (72 km/h) and can only travel 55 miles (88 km) on a single charge. So, it’s more of a fun recreational vehicle than the Café Racer motorbikes that have inspired it.
Mode Options for Varied Terrain
Three different driving modes are offered. The first, known simply as E-Bike Mode, caps the top speed to 20 mph (32 km/h) while Mopar Mode unlocks a top speed of 30 mph (48 km/h). The dedicated Off-Road Mode is needed to get to 45 mph (72 km/h).
Shoppers who need a little more than 55 miles of range can opt for a larger 3.6 kWh pack, boosting range to 70 miles (112 km). Both models include regenerative braking, and the battery can be charged to 80 percent in three hours from a normal household plug.
Classic Design
Visually, the Beachman ’64 ticks all the right boxes. It comes equipped with grippy off-road tires, slim motorcycle-style handlebars, and a prominent central headlight. A quilted leather seat adds a touch of vintage charm to the overall design.
In the US, pricing for the ’64 starts at $4,800. That puts it close to the cost of some entry-level gas motorcycles, but if you’re looking for an electric alternative with vintage style, the options are far more limited. While it may not be the most practical electric bike on the market, it’s certainly one of the more stylish.
Tesla is considering a smaller pickup aimed at international markets for wider global appeal.
The idea is gaining traction as Cybertruck sales underperform and utility demand grows.
The company’s VP says design teams are exploring concepts for carrying both people and cargo/
The Tesla Cybertruck can be called a lot of things, but a smashing sales success isn’t one of them. In fact, even Ford’s F-150 Lightning outsold it in the first half of the year. Despite that, the automaker might not be done with truck models.
Over the weekend, Lars Moravy, the company’s VP of Engineering, shared that a smaller truck could be on the table. That could open the door to bringing the Cybertruck’s distinctive design to a broader, global market.
At a Tesla owners and investors event in California, Moravy responded to a question about the idea of a smaller, more compact truck, saying, “We always talked about making a smaller pickup.” Specifically, the automaker knows that the Cybertruck, in its current form, is simply too big for some markets.
A Truck That Fits More Markets
Building a smaller truck wouldn’t just help expand Tesla’s footprint in the pickup segment. It could also meet needs the current lineup doesn’t quite address.
“I think in the future, as more and more of the robotaxi comes into the world, we look at those options and we think about, OK, that kind of service is useful not just for people, but also for goods,” said Moravy, according to Business Insider. This could be a signal that Tesla is looking to expand into the medium-truck or even small van segment.
Speaking specifically about the former, Moravy elaborated further, saying, “We’ve definitely been churning in the design studio about what we might do to serve that need for sure.”
Right now, Tesla doesn’t have anything that really fits into the category of ‘delivery vehicle.’ In fact, many of its remote service vehicles are small gas-powered vans. No doubt, it would prefer to service customer vehicles with one of its own.
Practicality could prove a big selling point, too. The Cybertruck isn’t selling the way Tesla hoped it would. Early adopters picked it up, but sales have stalled out. Plenty of folks see it as a lifestyle vehicle more than a tried-and-true pickup in the conventional sense. Perhaps a mid-size truck would be a way to crack back into the practicality market, the same way the Model Y did so where the Model X couldn’t.
Polestar 5 prototype spied testing near Borussia Dortmund’s training facility in Germany.
Some soccer players reportedly rode in the 872-hp dual-motor electric performance model.
The super sedan will target rivals like the Porsche Taycan, RS e-tron GT, and AMG GT EV.
It’s been three years since the long-awaited Polestar 5 made its dynamic debut at the Goodwood Festival of Speed as a heavily-disguised prototype. In that time, the Polestar range has grown to include the Polestar 3 and Polestar 4, and yet, we are still waiting for the sleek Polestar 5 sedan to hit the market.
Thankfully, the electric automaker continues to work on this new model. Roughly seven months after our spy photographers snapped it during testing in Scandinavia, a YouTuber and Carscoops reader filmed a Polestar 5 being tested in Germany.
Visually, this prototype resembles the others we’ve seen, except for the addition of a glistening white rear diffuser, rather than the more subtle black one. According to Sascha Pallenberg, who filmed the car, the Polestar 5 was filmed around the training area of Borussia Dortmund, one of Germany’s most decorated soccer teams.
Some players from the team even reportedly sat shotgun in the prototype for some short test rides, prompting speculation that Polestar may soon become one of the team’s sponsors.
Targeting High-Performance Rivals
Polestar will position the 5 as a rival to the Audi e-tron GT, Porsche Taycan, and the upcoming Mercedes-AMG GT 4-Door EV, recently previewed with a dramatic concept. In 2022, Polestar said its flagship sedan could deliver 872 hp and 664 lb-ft (900 Nm) through a pair of electric motors. It’s possible that power could be lifted slightly, particularly since the latest RS e-tron GT Performance delivers 912 hp, and the AMG could have upwards of 1,000 hp.
Regardless of the car’s final horsepower and torque figures, it should be an absolute straight-line weapon. Think 0-60 mph (100 km/h) in the low 3-second range, if not even slightly quicker.
Visually, the 5 will remain easily identifiable as a Polestar thanks to its aggressive split headlights and dramatic rear end with a full-width light bar. The interior will also remain similarly minimalist to other Polestar models, meaning the 5 will be mostly free of physical buttons and switches, as the vast majority of its controls will be found within the infotainment display.
Tesla’s new entry-level Model Y has been spotted for the first time.
The SUV loses interior and exterior features to bring the price down.
Gone are the panoramic roof, front light bar and rear touchscreen.
Tesla sales are in free-fall and the automaker doesn’t have any genuinely new product on the horizon ready to save the day. Instead, as Elon Musk himself hinted, Tesla is stripping features from the existing Model Y to build a more affordable SUV. Today, we got our first look at the no-frills EV that could cost as little as $36,000.
The de-contented Model Y was spied in China where Tesla is facing stiff competition from domestic rivals engaged in a fierce price war. Images show a prototype of the budget Y parked next to a regular version of the SUV featuring the facelifted ‘Juniper’ look that was revealed earlier this year.
Scaling Back the Juniper Touches Inside and Out
But Chinese reports and spy shots suggest some of the key Juniper features, the front light bar and full-width rear light strip, have been cut from the entry-level machine.
There are some important omissions inside, too, where rear-seat passengers might find themselves feeling rather more claustrophobic. And that’s not because there’s less rear space, but because it looks much darker in there. Tesla has junked the panoramic roof to cut costs, replacing it with a simple black panel.
Other features missing from the interior include the 8-inch rear compartment touchscreen and the console found on all other facelifted Model Ys. The new EV does have a console, but it’s split, the portion between the seats ending with a pair of open cupholders just after the armrest.
What’s Still Included, and What Might Not Be
The 15.4-inch touchscreen is still present, and another aspect of the new base car that won’t be simplified, China’s Autohome reports, is the ADAS. We expect the budget Y to come equipped with Autopilot, just like other trims, though whether Tesla will reduce the power and range remains to be seen. America’s current entry-level Model Y, the Long Range RWD does zero to 60 mph (97 kmh) in 5.4 seconds and has an EPA range of 357 miles (575 km).
That LR RWD is available for $37,490 in the US right now, but only thanks to a $7,500 tax credit that is being phased out in September – its MSRP is $44,990. By stripping out some of the luxuries Tesla hopes it can deliver a Model Y at a tax-credit price even after the subsidy has disappeared. Some reports have suggested the price could be a low as $36,000 when it goes on sale in the final few months of 2025.
Honda has revealed its smallest electric car, the N-One e:.
The tiny EV can be used to power a home or other devices.
Its single electric motor is expected to make 63 hp (47 kW).
It may be small in size, but Honda’s cute N-One e: prototype made a big splash at this month’s Goodwood Festival of Speed even if it didn’t make a lot of noise in the process. Now, the production version of this pint-sized electric car has made its official debut in Japan.
An electric kei microcar, the N-One e: is a slab-sided, high-roof, boxy city car with a friendly robot-like face and tiny wheels that make it look cute and gawky at the same time. Unlike the Goodwood car, which featured fender flares, the Japanese version goes without to ensure it complies with the kei rules that govern everything from external dimensions to power outputs.
Built for Kei Compliance
So although Honda hasn’t revealed much in the way of technical spec, we can be sure it measures less than 3,400 mm (133.9inches) long and produces no more than 63 hp (64 PS / 47 kW) from its single electric motor.
Its electric hardware is almost certainly shared with the taller N-Van e: revealed last year, which Honda claimed could travel 152 miles (245 km) on a charge – the N-One will eke out a few more miles than that. The N-Van accepts 50 kW DC charging, which is slow, but the small battery can be charged in around 30 minutes.
Simple, Practical Interior With Smart Touches
The N-One’s interior looks simple, but not totally basic, and we like the fact that there are plenty of physical buttons and a rotary volume dial on the media screen. The transmission selector on the console looks much like the one on Hondas familiar to us in Europe and the US, and a simple button to the right allows the driver to easily engage a one-pedal mode.
A shelf below the touchscreen provides an obvious place to leave your smartphone within easy reach of the charging port (no wireless charging here) and the rear seats fold flat with a 50:50 split to maximize practicality. But the real headline feature is the V2L function that allows owners to use the N-One to power their homes during outages or other devices like electric bikes or laptops.
V2L Capability Adds Real-World Utility
To use V2L, owners will need to purchase an adaptor from Honda’s accessory catalog, which also includes a dash-top LED indicator to let you know how full the battery is and a sporty cosmetic kit with twin Shelby-style stripes running front to back.
Japanese sales of the N-One begin this September, the same month Honda is expected to give the pint-sized EV its European debut at the IAA in Munich. Sadly, there are no plans to bring the car to the US.
Much of the country is deep in the middle of a heat wave right now. And every summer, Duane Stilwell's town in Arizona seems to get hotter. It has him worried — and he's not the only one. Since 1980, the average number of heat waves in the U.S has doubled and the average length of a heat wave season has increased from 40 days to 70. Future summers, experts say, will be even hotter. But why exactly is that happening, and what can people do to protect themselves from the heat?

Only 28% of EV owners got same-day service in 2024, down from 40% in 2023.
Nearly one third of EV owners say their service takes longer than gas vehicles.
Mobile EV service grew to 19 percent of owners using technicians at home.
As electric vehicle become more common, the conversation is shifting from how many are being sold to how well they’re being supported. A new study suggests that dealership service departments may not be keeping up.
Based on customer survey data, the report reveals that 82 percent of EV buyers are open to purchasing another one. What’s shocking, though, is that this high level of satisfaction comes despite 85 percent needing some form of dealership service within the first year.
In the first half of 2025, more than 607,000 electric vehicles were sold in the United States, setting a new record. That surge may partly reflect a rush to buy before federal incentives begin phasing out. Those growing adoption numbers might make a concerning statistic even more challenging, too. EV owners who were able to get same-day service for their cars dropped from 40 percent in 2023 to just 28 percent in 2024.
Wait Times Are Increasing
That’s one of many data points we’re learning about via a new study from CDK Global. It also tells us that owners who had to wait three days or more jumped from 9 percent to 14 percent between those two years.
Nearly a third of EV owners said servicing their electric vehicle took longer than a gas-powered one, with non-Tesla drivers feeling the wait more acutely. According to CDK, 34 percent of non-Tesla owners reported longer service times, compared to just 23 percent of Tesla owners. On the bright side, 53 percent of non-Tesla drivers said EV service cost less than gas vehicle maintenance, compared to 41 percent of Tesla owners.
“We know dealers are prepared for EV service, but our most recent findings show EV owners are waiting longer to have their cars serviced, and it’s taking multiple visits to have their issue resolved,” David Thomas, director of content marketing and automotive industry analyst at CDK, told Auto News.

SWIPE
While lots of owners had their issues fixed in a single trip, repeat visits to the dealer are on the rise. Just 65 percent of non-Tesla owners reported one-and-done service experiences. A whopping 21 percent needed four or five visits to fix their problem. That certainly sounds familiar, given some of the strange service issues we’ve covered here.
Not All the News Is Bad
The study isn’t without its upsides, though. Only 13 percent of EV owners said they had to pay out of pocket for service. 16 percent of appointments were recall-related, and that figure split evenly between Tesla and other brands.
Mobile service is also expanding, with 19 percent of owners reporting that a technician came to them to work on their car in 2024, up from 14 percent the year before. Dealer pickups are slowly gaining traction as well, climbing from 6 percent in 2023 to 9 percent in 2024.
Finally, it’s important to point out that this study is entirely based on customer surveys. These are electric vehicle owners, so while they do have first-hand experience, the data gathered here isn’t unquestionable. As is the case with any survey, bias is a major concern and almost certainly a factor in the results. That said, some statistics mentioned here, like how long service took, are likely good indicators of the average ownership experience.
Cybertruck owner returned from vacation to find his EV dead despite being plugged in.
Tesla quickly diagnosed a failed power converter and towed the truck for free repairs.
The company confirmed heat and charging were not the cause and covered repairs.
Imagine coming back home after a couple of weeks away to find your six-figure EV dead as a doornail. If it had been unplugged the whole time, slowly draining its battery, the situation might have made more sense. But in this case, the Cybertruck in question was connected to a charger the entire time.
When the owner, AJ Esguerra, returned to his Cybertruck after two weeks away, he realized it had been getting juice for almost two straight weeks. Parked in scorching-hot Arizona, he worried he’d fried something for good. One message to Tesla service ended up being all he needed.
Unexpected Silence After Two Weeks Plugged In
The initial worry for Esguerra was real. He posted to the Cybertruck Owner’s Club on Facebook looking for insight. “Need some help- we were on vacation for 2 weeks and just returned and the CT won’t power on at all. I looked at my app and it says it last connected 11 days ago,” he wrote.
Given the conditions, he thought perhaps the heat waves passing through Arizona might have come together with a constant trickle charge and ruined something on the truck.
“We’ve had record heat the past week. Is it possible it overheated and damaged the battery or can I try a master reset before I set up a service call,” he asked fellow owners. Responses were mostly kind but a few probably weren’t what he wanted to hear.
“It’s bricked bro…” said one person. “An insurance fire is the only solution,” said another. Thankfully, some folks provided reassurance and simply directed him to contact Tesla service. When he did, the ball rolled quickly downhill.
“Tesla service is on the way. Quick response through app and received a call immediately,” Esguerra says. From there, the technicians jumped the truck to life, towed it to a service center, and dug deeper.
The Real Culprit
What they found was that the power converter failed. According to AJ, it had nothing to do with charging the truck or the heat or the combination of the two. In fact, he says that Tesla told him to just leave it plugged in for as long as he wants.
“They recommend to keep it on the charger at all times. It will stop charging when it’s full. He said they have a lot of snowbirds with CTs that leave for months and keep it on the charger with no issues,” he says.
In a world full of cases where cars break and warranty or service work ends up being less than ideal, this is a nice break from that disappointment. AJ says he’s back on the road and that Tesla covered everything. That’s as happy an ending as one could hope for here.
The twilight zone of the ocean is a mysterious place. At 200-1000 meters below the surface, it's a tough place to study. That's why, during World War II, people reading sonograms from this zone were perplexed when it looked as if the ocean floor was moving up. Every day. And then back down again before dawn. In this latest installment of Sea Camp, we explore what this historical mystery has to do with the Earth's ability to cycle and store carbon in the ocean's watery depths.

Engineers have developed an EV battery housing built from wood to improve sustainability.
The steel-wood hybrid is greener than traditional aluminum structures and even stronger.
Cork is used for fire protection and helped the pack outperform a stock Tesla’s in lab tests.
Electric vehicles have made impressive strides in recent years, but several key design challenges remain. One of the most pressing is how to improve battery packs in a way that enhances both safety and long-term sustainability.
We’ve all seen images and videos of EVs being incinerated when their battery packs have caught fire. So if someone tried to tell you that they’d come up with a revolutionary new battery housing that’s made out of wood, well, you’d naturally think they’d inhaled too many combusting lithium cell vapors. But boffins are adamant that, when it comes to EV battery cases, wood is good both for the planet and for safety.
A study carried out at the Technical University of Graz in Austria compared the performance of a conventional underfloor battery housing built with aluminium beams with three different wood-steel hybrid versions. The team wanted to see if it could build a housing that was more environmentally friendly, but required no strength compromises.
Lighter Footprint, Solid Performance
The hybrid beams use sustainable birch, poplar or paulownia cores covered in thin, lightweight steel, giving them a much smaller environmental footprint than those made from aluminium, which is incredibly energy intensive to produce. That much they knew before they’d got to the lab. But it’s the other results that provided the real surprises.
In a critical pile crash test where a vehicle or component is driven into a round steel obstacle at high speed the hybrid Bio!Lib battery housings returned almost exactly the same intrusion values as the aluminum housing of a Tesla Model S. The reason is the wood’s porous cell structure helps it absorb great amounts of energy.
The poplar and birch steel hybrids delivered up to 98 percent more energy absorption than ductile aluminum and 76 percent more than high-strength aluminium under large deformations. All three wood-based versions also showed strong resistance to bending.
Organic fire-resistant material
And with the addition of cork – another renewable material – the study group led by TU Graz’s Florian Feist, was also able to make the housing usefully fire-resistant, returning temperatures on the off-fire side of the unit 100 degrees C (212 F) lower than on a Tesla housing.
“When cork is exposed to very high temperatures, it charses,” explains Florian Feist, who led the study. “The carbonization leads to a sharp drop in the already relatively low thermal conductivity, which protects the structures behind it.”
As electric vehicles become more common, it’s becoming clearer that their environmental impact goes beyond the absence of tailpipe emissions. While a wood-based battery case might seem unlikely, research like this highlights how smarter material choices could help EVs better deliver on their clean energy potential.
A Cybertruck owner says his pickup has sat at a service center for weeks with a squeak.
Tesla’s team has had the truck for 40 days straight without finding the source of the noise.
The owner now wants Tesla to buy back the truck or provide a brand-new replacement.
Beyond serious mechanical issues, squeaks and rattles rank high amongst the most annoying things one may have to deal with in any car. Imagine, though, if your ride had an incessant rattle or squeak despite it being basically brand new and costing six figures. That’s what one Cybertruck owner is dealing with right now, and Tesla seems incapable of fixing the electric pickup.
The owner first posted about his experience on Facebook in June: “My Cybertruck is in service for a squeak coming from the front left pillar near the windshield. The service team tried using foam and insulation, but couldn’t fix it,” he said. At that point, the team decided to send the truck to a collision center.
Ongoing Repairs With No Resolution
From there, things haven’t improved. In a newer post, he claims that the center has had the truck for 40 consecutive days without finding a fix. “They’ve replaced parts, added insulation, and tried multiple approaches, but the issue remains,” he says. That appears to include disassembling several components and reworking them to no avail. A message from Tesla service to the owner says it’s a top priority and that they’re working on it.
Interestingly, this doesn’t seem to be an isolated incident, as in the original post from June, several other owners claim to have similar issues.
“My CT has a rattling noise from the same area (front driver’s side dashboard / a-pillar area near front window) when going over bumps,” said another owner. “I have dashboard and pillar rattle and squeak too. This is third attempt to fix,” said another. “I’ve had so many creeks, squeaks, and rattles…. I’ve taken it in 5 times already,” said one more.
From Annoyance to Dealbreaker
Both ironically and sadly, one even admitted that it rattles so much that they just take a different car when they want a quiet ride. It sounds like that’s where the owner in this story is on his journey, too. He now wants Tesla to either buy the truck back altogether or for the automaker to give him a new one. There’s no telling if that one will squeak too though. We’ll follow this story and update you if we hear more.
Tesla begins limited Robotaxi testing in San Francisco with human safety drivers.
California rollout only allows employees, family, and select participants to ride.
The company requested expanded testing permits from California regulators recently.
Τesla is about to widen out its Robotaxi footprint, though that shouldn’t come as much of a surprise, seeing as Elon Musk recently said that “half of the population of the US will be covered by Tesla’s Robotaxi by the end of the year.” Well, everyone’s got to start somewhere, and now that the system is alive in Austin, Texas, it apparently is time to expand.
According to Business Insider, Tesla is about to roll out a similar, albeit heavily neutered, version of the program in California. Specifically, it’ll begin Robotaxi testing in San Francisco over the weekend. Just like the service in Austin, the shuttles will work within a geo-fenced area.
Testing With a Safety Net
Never a company away from pushing its limits, Tesla isn’t being conventional about this launch. Rather than release driverless Model Ys across all of San Francisco, it has put several caveats into the service. For instance, every ‘Robotaxi’ will come with a human behind the wheel.
That’s markedly different from what it’s doing in Austin and there’s a good reason for it. Tesla doesn’t have the legal ability to offer the kind of driverless service it does in Austin, in San Francisco. Notably, even the cars in Texas have a Tesla employee in the car, albeit in the front passenger seat.
It needs regulatory approval, and since it doesn’t have it, there must be a driver in the driver’s seat. Essentially, the way it sounds is that this is going to be akin to calling your friend who has FSD on a car and then letting him or her ferry you around while hopefully not needing to intervene while the car drives.
Pushing the Boundaries, Carefully
In addition, Tesla doesn’t have the regulatory freedom to offer autonomous rides to the general public in this manner. To that end, it’s only going to allow select members of the public, employees, and family members of employees into the testing program.
Basically, it seems as though it’s skirting the line regarding legality in just about every way that it can. Importantly, it reportedly requested a permit to extend its operations with the California Public Utilities Commission. It hasn’t yet applied to provide a commercial service to the public, though, so it appears as though all of this is in the very early testing phase.
RENO, Nev. – The Green Bus Summit at STN EXPO West was a gathering of enthusiastic minds to discuss the technology and training needed to achieve a clean energy future.
Advancing School Bus Innovation RIDE
Frank Girardot, senior vice president of electric school bus manufacturer RIDE Mobility, noted during a panel discussion that there is a sales job involved when transportation staff must convince district administration that electric school buses (ESBs) are a good investment.
Craig Beaver, administrator for transportation at Beaverton School District in Oregon, said his ESB journey began with grant writing and utility cooperation. Operationally, he said bus capacity, battery size and the reliability of the OEMs are of utmost importance. Beaverton assigned ESBs to certain routes, not specific drivers. Beaver, the 2024 STN Transportation Director of the Year, said even diesel devotees have come around to appreciate them.
Jim Snow, CEO of Mid-Placer Public Schools in rural northern California, has propane buses and is implementing electric buses. He noted that stacking federal and state funding is key. When choosing buses, he said to prioritize the needs of the students, which for his district means those with special needs.
Meanwhile, Jessica Sevilla, director of fleet and facilities for Antelope Valley Schools Transportation Agency in California, said that having the right staff, driver and mechanic training, and vendor relationships throughout the process is crucial so everyone feels supported. She advised leveraging futureproofing and AI tools in planning processes.
Rural Elko County School District in Nevada is just starting its electric bus journey with the use of grants and is currently participating in a V2G pilot program, which provides no-cost infrastructure. “We had to look at what was available and how it would meet our needs,” Director of Transportation Seth Canning said.
Jarrett Garife, manager of transportation for the rural Monterey (California) County Office of Education, applauded state funding and underscored the need for driver buy-in. He said he needed to buy a diesel bus to use for driver recertification during the ESB implementation process.
Girardot added that to successfully run operations, rural districts must consider things like route length, bus capacity, temperature changes and staff training. Several panelists said that rural milage challenges were assuaged by using DC fast chargers.
Panelists also agreed that good communication and training for drivers and mechanics is important to a successful ESB implementation. Beaver and Snow noted that drivers need to be specifically trained on things like regenerative braking and handling the extra weight of ESBs with heavy batteries.
Beaver said he eases his team’s trepidation with ESBs by reminding them, “It’s just a school bus.”

Fuel of Choice Blue Bird
Stephen Whaley, alternative fuels manager for Blue Bird Corporation, reviewed the upcoming California Air Resources Board (CARB) emissions reduction from 0.2 g/bhp-hr to 0.035 g/bhp-hr in 2027, the disruptive growth of alternative fuels in Blue Bird’s business and why school districts should consider clean fuels.
During a panel discussion he reviewed the stories of Kay Cornelius, transportation director for rural St. Louis County Schools in northern Minnesota, Diana Mikelski, director of transportation for District 211 in Illinois, and Anthony Jackson, executive director of transportation for Bibb County School District in Georgia, who praised propane school buses for their reliability and quiet operation as well as both fuel and maintenance savings.
Chris Horstman noted from his career experience – as a past school bus driver and current director of transportation for Ithaca City School District in New York – that misconceptions about propane and gasoline buses had to be overcome but that both have proved durable. Gas and propane both produced significant savings over diesel, he said.
Andrew Thompson, fleet manager for Boulder Valley School District in Colorado, runs mostly diesel, propane and gasoline. The district later acquired the state’s first electric school bus, which he said was met with some hesitation but did not require complicated infrastructure setup. The plan is to transition to 50 percent electric buses over 15 years. Thompson discussed his DC fast charger preferences and noted the differences between Level II and Level III chargers.
Both panelists agreed that maintenance professionals find the propane buses easier to work on.
Additionally, John Wyskiel, new president and CEO of Blue Bird, took the stage Monday morning, July 14, before magician Jon Petz’s keynote and recapped the OEM’s dedication to safety, demonstrated through the standardization of lap-shoulder belts, driver airbags, LED lighting, collision mitigation systems and more safety equipment. Blue Bird also supports propane and electric school bus deployment, with the most ESBs deployed in the U.S. — 2,500.
He praised Blue Bird’s partners, dealers and employees who help support school districts around the nation and reaffirmed a commitment to continued service in anticipation of the company’s upcoming centennial in 2027.
Your Route. Reimagined. Micro Bird
Alexandre Ratte, vice president of sales and marketing, recapped Micro Bird’s three generations of quality and safety and reiterated its commitment to progress and growth. Its gasoline, propane and electric solutions are all built in house.
Marc Gravel, general manager of Micro Bird’s electric subsidiary Ecotuned, next revealed that the G5e Type A electric school bus, which was introduced last year at STN EXPO West, is in full production with buses being delivered to customers. This bus was part of the STN EXPO West Ride and Drive event on Sunday evening in the parking lot of the Peppermill Resort Casino.
Two G5e options provide a choice of either 150- or 200-mile range. The lithium iron phosphate (LFP) battery packs come with an eight-year warranty and the buses can support both fast DC and AC charging. Vehicle to grid (V2G) technology and over the air updates are also supported.
Gravel shared that the G5e endured 100+ degree temperatures on a trip through the Mohave Desert, while also revealing valuable learning lessons about the need for increased charging infrastructure. The bus also performed well in negative 15-degree temperatures in Canada, he added.
Gravel reiterated the company’s dedication to customer service, borne out by the Micro Bird Academy and expert service available across 70 service locations throughout North America.

The Healthy, Cost-effective Route to School Transportation Propane Education & Research Council
Driving the Future with Cummins: Forging a Sustainable Outlook Cummins
“Clean energy is our future,” declared Richard Garvin, director of strategy and commercial business development for Cummins.
Francisco Lagunas, general manager for the Cummins North American bus market, reiterated the company’s support for the EV market. “Wherever you are in your electrification plans, we will meet you there – and we have a whole ecosystem to assist you,” he confirmed.
Matt McGinn, senior director of EV sales and business development for Cummins, noted that districts can see current energy market shifts as an opportunity to diversify rather than as an obstacle.
When it comes to future-proofing, Garvin added that securing funding sources like grants is a big part of it. McGinn said that the best solution for each district depends on its location and goals. Senior Gas Sales Executive Emilliano Pantner confirmed that Cummins is there to help no matter what bus or infrastructure combinations a district needs to achieve those goals.
Pantner, who also oversees microgrids, noted that districts should have a good handle on their current data and metrics to then develop a plan for clean energy that also aligns with operational and student needs. Garvin spoke about the patience that is needed for each district’s “Road to Zero,” which for Cummins has an achievement goal of 2050.
“This is going to be incremental rather than rapid,” he said. “We need to be transparent and collaborative to reach those goals.”
Comprehensive training, online resources and customer service are integral parts of Cummins’ offerings, panelists confirmed.
Attendees shared their concerns about rampant parts unavailability and questioned what Cummins is doing at the federal level to support EV funding for districts who have begun their electrification journeys and are now facing funding loss. Panelists confirmed Cummins’ efforts in parts tracking, grant seeking and federal lobbying, though they confirmed that some things in flux are out of their control. Cummins is always open to feedback and dedicated to improvement, they stated.

Innovative Parts Management Strategies, Solutions for Fleet Management IC Bus
“You guys have a lot going on and we want to come up with solutions that make your life easier and make you better at what you do,” said Alex Borror, sales director for IC Bus parent company International.
He shared how OnCommand Connection now comes standard on all IC Buses and allows mechanics visibility to alerts in real time so they can direct the driver to come in for service if needed. Though its focus is vehicle health, it also tracks GPS and driver behavior to allow for training opportunities. Electric school bus operators, especially, can find valuable insights in the dashboard and related app, Borror added.
He also shared that IC Bus dealers can help locate funding for electric and other types of buses through their Incentive Prospecting Tool. Additionally, Sourcewell is legally aligned with the OEM to help streamline the purchasing process.
Gregory Baze, national parts account manager for IC Bus, revealed feedback that school district maintenance professionals were spending a lot of time on the phone or internet trying to locate parts or putting together standard stock orders.
RepairLink is an ecommerce platform designed to help mitigate those pain points by allowing dealer customers to look up and order the parts they need on their own, at no extra cost. Benefits include time saved, greater inventory availability, real-time order updates, a VIN-based catalog, easy reorder of saved carts, and cost-saving promotions.
Baze noted that this service was a positive development due to the trend toward online purchasing which has made its way over to the school bus industry. Setup, search and ordering are easy, and there is a buyback program.
“We do more than sell buses,” Baze summed up. “If you’ve got a problem, don’t suffer through it alone.”
Attendees asked about whether parts can be tracked, like on Amazon, and Baze responded that technology is progressing quickly, with that feature planned for wide rollout. A question was presented on the shortage of electric bus mechanics from dealers, which panelists said is being temporarily alleviated through satellite service stations while district mechanic training is ramped up. Multiple attendees expressed the need for more ESB training, which Baze and Borror encouraged them to get from their dealers and the IC Bus University.
Powering the Future: Practical Insights for Electric Bus Charging EO Charging
“EV and school bus make a great marriage,” declared Brad Beauchamp, EV product segment leader for Blue Bird.
Adam Wilkum, North American sales director for UK-based turnkey provider EO Charging, noted that EV charging is an area where an ounce of prevention is worth a pound of cure. “Don’t be afraid of vendors,” he quipped.
Marc Riccio, vice president of strategic partnerships for comprehensive charging solutions provider Highland Electric Fleets, pointed out that a flawed infrastructure setup that lacks futureproofing and copious communication with partners wreaks havoc with timelines and budgets. He advised “patience, perspective and persistence” through the process.
Manny Huguez, president of charging technology provider Zerova Technologies, said vendor partnerships cover all bases and help districts not only set up but also optimize their new electrified operation. They must also be carefully chosen since businesses do leave the EV space, as in the case of the recently bankrupt bus manufacturer Lion Electric Company. Districts must be mindful and do their due diligence.
“Pick a partner, not a product,” he advised. “You have to be able to depend on them for the long run.”
Beauchamp reviewed several aspects districts should carefully consider, including Level II versus Level III charger choice and bus to charger interoperability.
Huguez underscored how mission critical such considerations are so students are not left stranded. “We aren’t delivering packages here,” he said. He added that training is being expanded so district mechanics can service ESBs instead of waiting hours for certified technicians to do so.
Riccio spoke on how the fixed schedules and timing of school bus routes, as well as the fact that buses are basically batteries on wheels, makes them ideal for vehicle to grid (V2G) and vehicle to everything (V2X) use cases or emergency response situations where the main electrical grid is down.
The panelists spoke to the ever-changing and improving nature of EV technology and looked to the future with optimism. Beauchamp stated that, despite federal Clean School Bus Program funding slowing down, EV isn’t going anywhere and will continue to grow.
