EV adoption spurs updated guidance on parking structure design
As electric vehicles (EVs) become increasingly common on roads around the world, many infrastructural changes will be needed to accommodate them. One example includes the design of parking garages, which some say will require updated fire safety protocols and additional modifications to accommodate the heavy weight of EVs.
The United Kingdom’s Institution of Structural Engineers released a new design guidance for parking garages earlier this year, pointing out a broad range of topics related to the structures, from EV weight, charging access and reduced noise levels to fire safety considerations (via CNBC). The guidance includes suggestions for the design of garages that are multi-story, underground or simply located inside offices or residential buildings.
Perhaps the most pressing topic included in the guidance for parking garages — called multi-story car parks in the U.K. — is the battery hardware used in EVs, which makes them much heavier than internal combustion engine (ICE) vehicles. With increased range models and a wider span of vehicle classes, EV weights will likely continue getting heavier in the future.
“This extra load and the changing fire safety requirements are all considerations not just for new car parks, but for existing structures too,” the institution writes in the report.
According to the group, average vehicle weights have increased from 1.5 metric tons (3,307 pounds) in 1974 to almost 2 metric tons (4,409 pounds) this year. As one example, Tesla’s forthcoming Cybertruck is a stainless steel behemoth, expected to weigh somewhere between 5,000 and 8,000 pounds (2.3 to 3.6 metric tons).
Institution fellow and co-author of the guidance Chris Whapples also notes that some newer EVs are well over 3 metric tons (6,614 pounds).
“The thing to bear in mind is that the ones that cause the damage, if you like, are the heavy vehicles — not the vehicles that are heavier than they were 40 years ago but still within the capacity of the design for car parks,” Whapples explained in an interview with CNBC. “We’re seeing increasing numbers now of SUVs, large executive cars — both fossil-fueled and battery ones — and pickup trucks, which are immensely heavy.”
Whapples details a handful of potential solutions for heavy vehicles, primarily including the need to retrofit older garages with increased structural support, either in specific spots that are determined to be weaker or in their entirety. He also notes that heavy vehicles could stay on ground floors to park, and garages could even screen the weights of cars as they enter.
“If one pickup is significantly overloaded and that car park is weak, that’s a potential disaster waiting to happen,” Whapples added. “We said, as an industry, we must actually check our car parks out and make sure that that’s not going to happen. Because what we want is the public to maintain confidence in our car parks and structural engineers.”
Another top concern detailed in the guidance was improving fire safety protocols in parking garages. Whapples notes that fire risks aren’t exclusive to EVs, adding that gasoline cars can also start fires and make situations more complicated. While EV fires aren’t considered more common than ICE vehicle fires, they can be especially tough to put out, he explains.
“To actually extinguish an EV fire is very, very difficult — particularly if the battery is on fire, because you’ve got so much energy that’s locked in,” Whapples said.
As for potential solutions, Whapples says that sprinkler systems could be an important way to mitigate fire spread, especially in underground car parks.
“Although the sprinkler system will not put out the car fire, it will reduce the rate of spread within the car park, so it’s constantly … ‘quenching’ the car next to the one that’s on fire, and stopping that one from catching fire,” Whapples explains.
All of these and more points will need to be considered ahead of mass EV adoption, both for existing garages and newly built construction. The International Energy Agency (IEA) expects EVs, buses, vans and heavy trucks to reach as many as 145 million units globally by 2030, though government ramp-up efforts could boost that number even more. In 2022, 10 million EVs were sold, including plug-in hybrids and battery-electric vehicles.
The discussions come ahead of Tesla’s initial release of the Cybertruck, which has been widely discussed for its large size, among other details. If many EVs are physically larger than ICE vehicles in the future, it could also require garages to be built with similarly larger parking spaces. Tesla has rolled out some wider and longer parking spaces at its Supercharger stations for the Cybertruck, a move that may be necessary for all parking structures down the road.

Tesla hints at Starlink integration with recent patent
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
Tesla hinted at a potential Starlink internet terminal integration within its vehicles in a recent patent, which describes a vehicle roof assembly with integrated radio frequency (RF) transparency.
The patent, which is Pub. No U.S. 2025/0368267 describes a new vehicle roof that is made of RF-transparent polymer materials, allowing and “facilitating clear communication with external devices and satellites.”
Tesla believes that a new vehicle roof design, comprised of different materials than the standard metallic or glass elements used in cars today, would allow the company to integrate modern vehicular technologies, “particularly those requiring radio frequency transmission and reception.
Tesla has recently filed a US patent application on integrating RF transparent materials into the roof structure.

Instead of glass or metallic materials, Tesla says vehicles may benefit from high-strength polymer blends, such as Polycarbonate, Acrylonitrile Butadiene Styrene, or Acrylonitrile Styrene Acrylate.
These materials still provide ideal strength metrics for crashworthiness, stiffness for noise, vibration, and harshness control, and are compliant with head impact regulations.
They would also enable better performance with modern technologies, like internet terminals, which need an uninterrupted signal to satellites for maximum reception. Tesla writes in the patent:
“By employing polymer blends, some examples enable RF transmission from all the modules to satellites and other communication devices both inside and outside the vehicle.”
One of the challenges Tesla seems to be aware of with this type of roof design is the fact that it will still have to enable safety and keep that at the forefront of the design. As you can see in the illustration above, Tesla plans to use four layers to increase safety and rigidity, while also combating noise and vibration.
It notes in the patent that disclosed examples still meet the safety requirements outlined in the Federal Motor Vehicle Safety Standards (FMVSS).
Starlink integrated directly into Tesla vehicles would be a considerable advantage for owners. It would come with a handful of distinct advantages.
Initially, the inclusion of Starlink would completely eliminate cellular dead zones, something that is an issue, especially in rural areas. Starlink would provide connectivity in these remote regions and would ensure uninterrupted service during road trips and off-grid adventures.
It could also be a critical addition for Robotaxi, as it is crucial to have solid and reliable connectivity for remote monitoring and fleet management.
Starlink’s growing constellation, thanks to SpaceX’s routine and frequent launch schedule, will provide secure, stable, and reliable internet connectivity for Tesla vehicles.
Although many owners have already mounted Starlink Mini dishes under their glass roofs for a similar experience, it may be integrated directly into Teslas in the coming years, either as an upgrade or a standard feature.

Tesla supplements Holiday Update by sneaking in new Full Self-Driving version
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla has surprised some owners by sneaking in a new Full Self-Driving version with the wide release of the Holiday Update, which started rolling out to Hardware 4 owners on Friday night.
Tesla has issued a controlled and very slow release pattern with the Holiday Update, which rolls out with Software Version 2025.44.25.5.
For the past two weeks, as it has rolled out to Hardware 3 and older Tesla owners, the company has kept its deployment of the new Software Version relatively controlled.
It seems Tesla was waiting for the Hardware 4 rollout, as it wanted to also deploy a new Full Self-Driving version to those owners, as it appeared in the release notes for the Holiday Update last night.
Tesla Full Self-Driving v14.2.1.25 made its first appearance last night to Hardware 4 owners who are members of the Early Access Program (EAP). It appears to be a slight refinement from FSD v14.2.1, which has been out for a couple of weeks.

Many owners welcome the new FSD version, us included, because we’ve been less than impressed with v14.2.1. We have experienced some minor regressions with v14.2.1, especially with Speed Limit recognition, Speed Profile tinkering, and parking performance.
As it stands, Full Self-Driving is still particularly impressive, but Tesla is evidently having an issue with some of the adjustments, as it is still refining some of the performance aspects of the suite. This is expected and normal with some updates, as not all of them are an improvement in all areas; we routinely see some things backtrack every once in a while.
This new FSD version is likely to take care of those things, but it also includes all of the awesome Holiday Update features, which include:
- Grok with Navigation Commands (Beta) – Grok will now add and edit destinations.
- Tesla Photobooth – Take pictures inside your car using the cabin-facing camera
- Dog Mode Live Activity – Check on your four-legged friend on your phone through periodic snapshots taken of the cabin
- Dashcam Viewer Update – Includes new metrics, like steering wheel angle, speed, and more
- Santa Mode – New graphics, trees, and a lock chime
- Light Show Update – Addition of Jingle Rush light show
- Custom Wraps and License Plates – Colorizer now allows you to customize your vehicle even further, with custom patterns, license plates, and tint
- Navigation Improvements – Easier layout and setup
- Supercharger Site Map – Starting at 18 pilot locations, a 3D view of the Supercharger you’re visiting will be available
- Automatic Carpool Lane Routing – Navigation will utilize carpool lanes if enabled
- Phone Left Behind Chime – Your car will now tell you if you left a phone inside
- Charge Limit Per Location – Set a charge limit for each location
- ISS Docking Simulator – New game
- Additional Improvements – Turn off wireless charging pad, Spotify improvements, Rainbow Rave Cave, Lock Sound TRON addition
Tesla also added two other things that were undocumented, like Charging Passport and information on USB drive storage to help with Dashcam.
Tesla is updating Cybertruck owners on its timeline of a massive feature that has yet to ship: Powershare with Powerwall.
Powershare is a bidirectional charging feature exclusive to Cybertruck, which allows the vehicle’s battery to act as a portable power source for homes, appliances, tools, other EVs, and more. It was announced in late 2023 as part of Tesla’s push into vehicle-to-everything energy sharing, and acting as a giant portable charger is the main advantage, as it can provide backup power during outages.
Cybertruck’s Powershare system supports both vehicle-to-load (V2L) and vehicle-to-home (V2H), making it flexible and well-rounded for a variety of applications.
However, even though the feature was promised with Cybertruck, it has yet to be shipped to vehicles. Tesla communicated with owners through email recently regarding Powershare with Powerwall, which essentially has the pickup act as an extended battery.
Powerwall discharge would be prioritized before tapping into the truck’s larger pack.
However, Tesla is still working on getting the feature out to owners, an email said:
“We’re writing to let you know that the Powershare with Powerwall feature is still in development and is now scheduled for release in mid-2026.
This new release date gives us additional time to design and test this feature, ensuring its ability to communicate and optimize energy sharing between your vehicle and many configurations and generations of Powerwall. We are also using this time to develop additional Powershare features that will help us continue to accelerate the world’s transition to sustainable energy.”
Owners have expressed some real disappointment in Tesla’s continuous delays in releasing the feature, as it was expected to be released by late 2024, but now has been pushed back several times to mid-2026, according to the email.
Foundation Series Cybertruck buyers paid extra, expecting the feature to be rolled out with their vehicle upon pickup.
Cybertruck’s Lead Engineer, Wes Morrill, even commented on the holdup:
As a Cybertruck owner who also has Powerwall, I empathize with the disappointed comments.
To their credit, the team has delivered powershare functionality to Cybertruck customers who otherwise have no backup with development of the powershare gateway. As well as those with solar…
— Wes (@wmorrill3) December 12, 2025
He said that “it turned out to be much harder than anticipated to make powershare work seamlessly with existing Powerwalls through existing wall connectors. Two grid-forming devices need to negotiate who will form and who will follow, depending on the state of charge of each, and they need to do this without a network and through multiple generations of hardware, and test and validate this process through rigorous certifications to ensure grid safety.”
It’s nice to see the transparency, but it is justified for some Cybertruck owners to feel like they’ve been bait-and-switched.
