Tesla and EVs’ popularity pushes car carrier companies to seek higher weight limits
With the transition to electric vehicles now inevitable, car carrier companies are urging politicians and the Biden administration to raise the truck weight limitations on the United States’ highways. By doing so, car carrier companies could transport more electric vehicles. But inasmuch as the proposal seems sound, the rail sector and safety activists strongly oppose the idea, with critics arguing that heavier trucks mean more dangerous roads.
It should be noted that even before electric vehicles like the Tesla Model 3 and Model Y became mainstream, American vehicles were already getting heavier. According to the Environmental Protection Agency (EPA), the average weight of automobiles and trucks on US highways has grown from 3,200 pounds to 4,200 pounds during the last 40 years. That was far before vehicles like the Tesla Model S surged in popularity.
For now, electric vehicles comprise less than 1% of the cars on US roads, but US President Joe Biden and his administration have pushed for half of vehicle sales by 2030 to be comprised of EVs. This is great for the environment, but pushing more EVs has an aftereffect of sorts. Since electric cars are heavier than their combustion-powered counterparts due to their large batteries, car carrier companies simply cannot transport as many of them as quickly under the current weight limits for car carrier trucks on the road, according to an Autoblog report.
Sarah Amico, executive chairman of Jack Cooper, one of the largest car carrier companies in North America, outlined some risks that come if the US government’s road weight limits maintain the status quo. “The truth is we will not be able move as many electric vehicles under the current weight limit. That could mean more trucks on the road, delays in orders, and increased costs,” Amico said.
Trailers in the United States today are restricted by federal highway safety standards to 80,000 pounds gross vehicle weight. And with the growing prevalence of EVs, the car hauling industry has pushed its lobbying efforts in an attempt to update the restrictions. The effort has some supporters, such as Illinois Republican lawmaker Rodney Davis, who serves on the House Transportation Committee. Davis noted that the auto transporter industry is looking to raise the weight limit on roads by about 5-10%.
“The auto transporter industry needs a modest 5% to 10% weight variance. Otherwise, an already-challenged supply chain will require more tractor-trailer rigs on the nation’s highways to deliver the same number of finished vehicles. That means more miles driven, more wear and tear on our roads, more fuel used, and more emissions,” he said.
While an extra 8,000 pounds may not sound like much, it could be the difference maker that could allow transporters to carry the same number of EVs as their ICE-powered counterparts. The Ford F-150 Lightning is about 1,600 pounds heavier than its gas-powered sibling, for example, and the Volvo XC40 Recharge SUV weighs about 1,000 pounds more than the combustion-powered Volvo XC40.
The efforts of car carrier companies, however, have met strong opposition from critics. Among these critics are the companies’ rivals in the freight rail industry, as well as safety experts who argue that heavier trucks are more difficult to stop, easier to roll, and cause more wear and tear on roads. Cathy Chase, President of Advocates for Highway and Auto Safety, mentioned some of these reservations. “With any incremental change comes incremental danger, and that results in more fatalities,” Chase said.
But while the concerns of skeptics are reasonable, the use of all-electric trucks like the Tesla Semi should address a number of safety concerns about heavier vehicles on the road. Electric trucks, after all, utilize systems such as regenerative braking to help the vehicles stop safely. The rollout of systems like Autopilot and FSD could also be a difference-maker in the safety of trucks, as they could ensure that pedestrians and other commuters are as safe as possible on the road.

A Tesla Semi caught fire in Hayward, California, which caused both directions of traffic to shut down for hours before being completely reopened early on Wednesday, the California Highway Patrol said.
The fire occurred just after 5:30 local time in Hayward on Tuesday, as the Semi caught fire in the southbound lanes of I-880 before CHP officials made the decision to shut down both lanes of traffic due to potential risks from hazardous chemical smoke.
There were no injuries reported.
🚨 A Tesla Semi reportedly caught fire, with California Highway Patrol confirming. The Semi was on I-880 SB
An estimated 5,000 to 7,000 semi-truck and large commercial vehicle fires occur on U.S. roadways every year

The cause of the fire is currently unknown, as neither Tesla nor the CHP have not determined a cause.
However, some images taken before the Semi was completely destroyed by the fire seem to indicate this might have been an older unit, as it appears to be one of the designs that Tesla shipped as part of its pilot program, before revising it and starting mass production just a month ago.
@Tslachan From on of the videos looks like it’s an old Semi (not the refresh version that recently started production) https://t.co/KzwmR2kXow

At the time of publication, CHP had not returned our request for a comment for additional details, including the Semi involved and any potential collaboration on an investigation between the CHP and Tesla. We will update this story when we hear back from them.
The southbound lanes were reopened at 3:30 a.m. on Wednesday, with the northbound lanes opening last night a few hours after the fire began. The CHP did state that the lithium batteries were “incredibly difficult to extinguish,” according to NBC Bay Area.
The truck’s driver said that the Semi caught fire, but he did not have an explanation.

Tesla’s launch of the “Emergency Drive Away” function a few months back offered owners a safe option to evacuate an area if they were in reasonable danger. The function finally got its first use in the real world, but it appears it was by mistake.
A video shared by u/Joshalander in the r/TeslaLounge subreddit recorded the instance from his vehicle and said the incident took place in Austin this past weekend during the city’s F1 Race.
“Was charging around 6 AM this past Sunday in Austin before heading to the F1 race and heard a pop. Looked over and saw the new emergency drive-away feature in action. Genuinely felt bad for the dude when he got out and realized what happened, since he looked exhausted and only seemed to half-read the prompts.”
🚨 Here’s the first look at Tesla’s Emergency Drive Away function in action:
Apparently this driver accidentally enabled it and drove forward; you can see the Supercharger pull with the car.
Tesla said previously this would cost up to $25k if not used properly. https://t.co/B4qQRrsO6B

Emergency Drive Away unlatches the Supercharger connector from the vehicle, but still causes damage to both the car and the Supercharger. Tesla has said that it will cost up to $25,000 in repairs to have everything fixed back to normal.
Additionally, the company said that if it were not used in an emergency situation, the driver of the vehicle who activated the Emergency Drive Away feature would be responsible for all repair costs.
Tesla constitutes the following situations as reasonable justifications for activating the feature:
- You face an immediate threat to your life or personal safety.
- You must leave the area immediately.
- Exiting the vehicle is unsafe.
- Unplugging the charge connector would unreasonably delay your departure or expose you to a risk to your personal safety.
After using the feature, Tesla requires the driver to schedule Service so the car can be inspected.

Tesla’s Cybercab battery design could make robotaxis even cheaper
Tesla built the Cybercab’s battery pack with spare room for a future switch to LFP.
Tesla built the Cybercab’s battery pack with empty space inside it on purpose, and the reason points to a cheaper robotaxi down the road.
Robert Sumpf, Tesla’s director of mechanical design engineering for battery modules and packs, said the extra room beside and beneath the Cybercab’s modules was left there so the company can move to lithium iron phosphate cells later. “So, we protected this pack to go to an even lower energy dense chemistry as we scale and need to bring LFP into the platform,” Sumpf said in a Cybercab deep dive with Munro Live.
The Cybercab runs on Tesla’s own 4680 cells with a nickel chemistry today. LFP cells store less energy for their size, so a straight swap would cut range. The reserved space lets Tesla add more LFP cells to make up the difference. In return, Tesla would get cells that cost less, run cooler and survive more charge cycles. LFP became the most used EV battery chemistry in the world last year.
Not all of that room was planned for a chemistry change. Lars Moravy, Tesla’s Vice President of Vehicle Engineering, said part of it exists because “we didn’t need as many batteries as we thought we did.” Tesla told Sandy Munro in early 2025 that it was targeting a Cybercab pack under 50 kWh with close to 300 miles of range.
The pack also breaks from the structural design Tesla used in some Model Y and Cybertruck builds. Instead of potting hundreds of cells into one block, the Cybercab uses four separate, individually sealed modules, so a bad module can be replaced without scrapping the whole pack. Sumpf was blunt about the older approach, giving the Model Y structural battery “a grade D” because it was hard to build and nearly impossible to repair. He estimated a fully structural pack gains about 10% more cell volume, but said “the issue is the service cost.”
That cost matters more for a car that rarely sits parked. Cybercab chief engineer Eric Earley said replacing an entire pack “before half a million miles is a killer on cost,” which is why remanufacturing and serviceability were built into the design from the start.
The same Munro Live tour produced Moravy’s admission that the Cybercab line at Giga Texas is now outpacing Robotaxi deployments, along with a look at the robotaxi’s unorthodox paint process. Tesla is aiming to deliver the first Cybercabs to outside customers by the end of 2026, though Elon Musk has said the vast majority will stay owned by Tesla and run as a transport service.
Sumpf did not give a date for an LFP version, name a cell supplier or say how a chemistry change would affect range. For now, the 4680 cars keep piling up: Texas DMV records from Tuesday list 544 Cybercabs authorized for Tesla’s Robotaxi fleet, more than the 507 Model Ys on the same roster for the first time.
