Tesla may soon support applying the brakes automatically when regen is limited
Forbes
It's challenging to determine Tesla's best feature or the one that has changed driving habits the most, but regenerative braking must be high on the list for anyone who owns an electric vehicle.
After getting accustomed to the system, the brake pedal becomes obsolete.
However, that piece of metal to the left of the accelerator is quickly remembered during cold temperatures or when the battery is fully charged and regenerative braking is reduced or not available.
A feature found in Tesla's latest update (2022.16) appears to address that issue by adding an option to make the car perform the same with or without regenerative braking.
When regenerative braking is reduced and the driver lets off the accelerator pedal the car will automatically apply its regular brakes. This gives the driver a consistent driving experience whether regenerative braking is fully available or limited.
Regenerative braking is one of the most significant factors that make electric vehicles so efficient. While in motion, if the driver applies less pressure to the accelerator or lifts their foot nearly off the pedal to decelerate, most EVs will slow down like the brakes are being applied, but they are not.
This one-foot driving style saves the use of brake pads and sends a charge back to the battery, creating additional energy. Tesla believes this is such an important feature it made the strongest regenerative braking mode standard in 2020.
However, if the car is fully charged, the battery will not take more energy. This system has also been known to act differently in cold climates.
Now, thanks to the 2022.16 update, during those circumstances, specific Tesla's Model 3s and Model Ys will perform the same without the ability to engage regenerative braking.
In the release notes, Tesla stated, "Your car can now automatically apply regular brakes for consistent deceleration when regenerative braking is limited due to battery temperature or state of charge."
According to @greentheonly, this feature is only available on limited Model 3s and Model Ys with specfic hardware. It's possible that Tesla is testing out the feature on very limited hardware or specific vehicles before making it available more broadly in a future update.
Understandably, some drivers may be turned off by the car blending in the brakes without the driver specifically pressing the brake pedal, so Tesla has made this feature optional.
If drivers want to be reacquainted with their brake pedal, then they don't need to enable the new feature; for those who do: tap Controls > Pedals & Steering > Apply Brakes When Regenerative Braking Is Limited. But, again, this is only available for select Model 3 and Model Y vehicles.
There's no news on when it will be made available for more broadly.
Another change came through on the latest over-the-air update, so subtle you may not have realized it was there.
After reading this, you may want to check out the display's top left corner. There is a line that is directly above the speedometer. Maybe you've noticed it before and not given it a second glance, but the line provides some valuable information.
The line is in the center if the car is not using or gaining energy, but it turns black during acceleration and green during regenerative braking.
You're not alone if you haven't noticed it or ignored it, as Tesla has made the line thicker and easier to see. This update is also only available for Model 3 and Model Y Teslas.

With Tesla’s first major expansion of the Robotaxi Geofence now complete and operational, they’ve been hard at work with validation in new locations - and some are quite the drive from the current Austin Geofence.
Validation fleet vehicles have been spotted operating in a wider perimeter around the city, from rural roads in the west end to the more complex area closer to the airport. Tesla mentioned during their earnings call that the Robotaxi has already completed 7,000 miles in Austin, and it will expand its area of operation to roughly 10 times what it is now. This lines up with the validation vehicles we’ve been tracking around Austin.
Based on the spread of the new sightings, the potential next geofence could cover a staggering 450 square miles - a tenfold increase from the current service area of roughly 42 square miles. You can check this out in our map below with the sightings we’re tracking.
If Tesla decides to expand into these new areas, it would represent a tenfold increase over their current geofence, matching Tesla’s statement. The new area would cover approximately 10% of the 4,500-square-mile Austin metropolitan area. If Tesla can offer Robotaxi services in that entire area, it would prove they can tackle just about any city in the United States.
From Urban Core to Rural Roads
The locations of the validation vehicles show a clear intent to move beyond the initial urban and suburban core and prepare the Robotaxi service for a much wider range of uses.
In the west, validation fleet vehicles have been spotted as far as Marble Falls - a much more rural environment that features different road types, higher speed limits, and potentially different challenges.
In the south, Tesla has been expanding towards Kyle, which is part of the growing Austin-San Antonio suburban corridor spanning Highway 35. San Antonio is only 80 miles (roughly a 90-minute drive) away, and could easily become part of the existing Robotaxi area if Tesla obtains regulatory approval there.
In the East, we haven’t spotted any new validation vehicles. This is likely because Tesla’s validation vehicles originate from Giga Texas, which is located East of Austin. We won’t really know if Tesla is expanding in this direction until they start pushing past Giga Texas and toward Houston.
Finally, there have been some validation vehicles spotted just North of the new expanded boundaries, meaning that Tesla isn’t done in that direction either. This direction consists of the largest suburban areas of Austin, which have so far not been serviced by any form of autonomous vehicle.
Rapid Scaling
This new, widespread validation effort confirms what we already know. Tesla is pushing for an intensive period of public data gathering and system testing in a new area, right before conducting geofence expansions. The sheer scale of this new validation zone tells us that Tesla isn’t taking this slowly - the next step is going to be a great leap instead, and they essentially confirmed this during this Q&A session on the recent call. The goal is clearly to bring the entire Austin Metropolitan area into the Robotaxi Network.
While the previous expansion showed off just how Tesla can scale the network, this new phase of validation testing is a demonstration of just how fast they can validate and expand their network. The move to validate across rural, suburban, and urban areas simultaneously shows their confidence in these new Robotaxi FSD builds.
Eventually, all these improvements from Robotaxi will make their way to customer FSD builds sometime in Q3 2025, so there is a lot to look forward to.
For years, the progress of Tesla’s FSD has been measured by smoother turns, better lane centering, and more confident unprotected left turns. But as the system matures, a new, more subtle form of intelligence is emerging - one that shifts its attention to the human nuances of navigating roads. A new video posted to X shows the most recent FSD build, V13.2.9, demonstrating this in a remarkable real-world scenario.
Toll Booth Magic
In the video, a Model Y running FSD pulls up to a toll booth and smoothly comes to a stop, allowing the driver to handle payment. The car waits patiently as the driver interacts with the attendant. Then, at the precise moment the toll booth operator finishes the transaction and says “Have a great day”, the vehicle starts moving, proceeding through the booth - all without any input from the driver.
If you notice, there’s no gate here at this toll booth. This interaction all happened naturally with FSD.
While the timing was perfect, the FSD wasn’t listening to the conversation for clues (maybe one day, with Grok?) The reality, as explained by Ashok Elluswamy, Tesla’s VP of AI, is even more impressive.
It can see the transaction happening using the repeater & pillar cameras. Hence FSD proceeds on its own when the transaction is complete 😎
FSD is simply using the cameras on the side of the vehicle to watch the exchange between the driver and attendant. The neural network has been trained on enough data that it can visually recognize the conclusion of a transaction - the exchange of money or a card and the hands pulling away - and understands that this is the trigger to proceed.
The Bigger Picture
This capability is far more significant than just a simple party trick. FSD is gaining the ability to perceive and navigate a world built for humans in the most human-like fashion possible.
If FSD can learn what a completed toll transaction looks like, it’s an example of the countless other complex scenarios it’ll be able to handle in the future. This same visual understanding could be applied to navigating a fast-food drive-thru, interacting with a parking garage attendant, passing through a security checkpoint, or boarding a ferry or vehicle train — all things we thought that would come much later.
These human-focused interactions will eventually become even more useful, as FSD becomes ever more confident in responding to humans on the road, like when a police officer tells a vehicle to go a certain direction, or a construction worker flags you through a site. These are real-world events that happen every day, and it isn’t surprising to see FSD picking up on the subtleties and nuances of human interaction.
This isn’t a pre-programmed feature for a specific toll booth. It is an emergent capability of the end-to-end AI neural nets. By learning from millions of videos across billions of miles, FSD is beginning to build a true contextual understanding of the world. The best part - with a 10x context increase on its way, this understanding will grow rapidly and become far more powerful.
These small, subtle moments of intelligence are the necessary steps to a truly robust autonomous system that can handle the messy, unpredictable nature of human society.
