FSD Beta V11 will be Tesla's next major FSD update
@xXIczNZWJUuJmGv
Stop me if you’ve heard this before, but Elon Musk says Version 11 of Full Self Driving will be released in two weeks. Tesla’s CEO has promised the long-awaited FSD V11 a few times. Most observers were certain it would be part of the Holiday update, but here we are in the second week of 2023 without Version 11.
However, unprompted, Musk responded to a general tweet about Tesla and the stock price. Musk tweeted: Looks like V11.3 will be ready for wide release in about 2 weeks. Many major improvements.
Improved Highway Autopilot
This is the build that has been touted by the CEO as the big one for several months now. The big change in FSD Beta V11 will be the new highway Autopilot experience. Tesla is leveraging and adapting the neural nets they use for city driving to highway driving. Navigate on Autopilot hasn't seen many advances in the last few years, but that's expected to change with this update.
Highway driving is notably easier than city driving, but when Tesla finally merges the two tech stacks we should see several improvements to Navigate on Autopilot, including smoother lane changes, merges and better transitions when entering or exiting the highway.
FSD Beta V11.3 may also finally include Tesla's 'reverse creep' feature which has been talked about for some time. This will allow the vehicle to reverse and readjust or move out of dangerous situations.
Release Notes
The FSD V11 release notes were partially leaked in November. However, there are likely now even more improvements in V11.3. The notes for V11 stated:
Enabled FSD Beta on highway. This unifies the vision and planning stack on and off-highway and replaces the legacy highway stack, which is over four years old. The legacy highway stack still relies on several single-camera and single-frame networks, and was setup to handle simple lane-specific maneuvers. FSD Beta's multi-camera video networks and next-gen planner, that allows for more complex agent interactions with less reliance on lanes, make way for adding more intelligent behaviors, smoother control and better decision making.
Improved Occupancy Network's recall for close by obstacles and precision in severe weather conditions with a 4x increase in transformer spatial resolution, 20% increase in image featurizer capacity, improved side camera calibration, and 260k more video training clips (real-world and simulation).
It's Unknown Who Gets FSD Beta V11
It’s unclear who's getting FSD Beta V11 in two weeks. Will it include a wider range of employees, or will it go to the OG beta testers as well?
With the latest Tesla updates, it appears Tesla has finally merged FSD Beta software and production builds, meaning that FSD Beta is available to everyone in the U.S. and Canada. However, does that mean all FSD Beta users will get v11 right away? Likely not, as Tesla will probably want to roll it out slowly and release minor revisions before everyone has access to it.
What to Expect
Expectations are key. Whenever Elon Musk communicates a date, that is often the best-case scenario and delays are a real possibility.
We may see the first glimpse of FSD Beta V11 in two to three weeks, but it'll likely be in limited numbers.
We know that Tesla employees were testing V11 in November. At that time, it was believed that the program would soon roll out to a small group of public testers to get more input.
We don't know just how far into testing V11 has been. But for Musk, who has been busy with Tesla, Twitter, and SpaceX, to take the time to again give an update and a timeline for V11, the most advanced FSD yet must be coming soon. Right?

Tesla has released software update 2025.2.6, and while minor updates typically focus on bug fixes, this one introduces a major new feature. With this update, Tesla has activated the in-cabin radar, a sensor that has been included in some vehicles for more than three years but remained unused until now.
Why Not Vision?
Unlike vision-based systems, radar can precisely measure object dimensions and even detect movement behind obstacles by bouncing radio waves off surrounding surfaces. This allows for more accurate and reliable measurements of objects that vision may not even be able to see, such as behind the front seats.
What Tesla Announced
Tesla recently highlighted the 4D radar in the new Model Y, explaining how it will improve passenger safety. Tesla executives stated that the radar would be used to properly classify passengers and improve the way airbags deploy.
Tesla went on to say that in a future update, Tesla will use the in-cabin radar to detect any potential passengers left in the vehicles. Since radar can even pick up on heartbeat and breathing patterns, it can provide a much more accurate method of detecting children left in a vehicle. Tesla talked about how the vehicle will send owners a notification via the Tesla app and enable the HVAC system if it detects a passenger in the vehicle. It’ll even call emergency services if needed.
New Feature in Update 2025.2.6
Tesla has officially named this feature in update 2025.2.6, “First-Row Cabin Sensing Update,” which appears to align with the first portion of what Tesla discussed in the new Model Y video.
In the release notes, Tesla describes the update as:
“The first-row cabin sensing system has been updated to use cabin radar, which is now standard in all new 2025 Model Ys. Your Model Y was built pre-equipped with the necessary hardware, allowing Tesla to also bring this technology to your vehicle.”
For now, it appears that Tesla is using the radar to detect and classify passengers in the front seats. This could eventually replace traditional seat sensors, reducing the number of hardware components and lowering production costs.
Tesla plans to expand the feature later this year, bringing rear-seat passenger detection in Q3 2025. While Tesla talked about the feature for the new Model Y, we expect it to be available for all vehicles with the in-cabin radar.
Supported Models
Although Tesla is vague in their release notes, this feature is being added to all Model Ys that include a cabin radar. Tesla started including the cabin radar in 2022, but its availability may vary by region and model. The Model 3 didn’t receive the cabin radar until it was redesigned in 2024, while all Cybertrucks already include it.
The owner’s manual for the redesigned Model S and Model X doesn’t specifically mention the interior radar, although Greentheonly believes the vehicles also include one, so we’ll have to wait to determine whether those vehicles also receive this new feature.
At this time, the feature appears to be only going out to Model Y vehicles, but we expect it to become available on other supported models soon.
We love to see these kinds of updates. Tesla is increasing the safety of existing and new vehicles through a software update while also making them more affordable to own.
Tesla has updated the Tesla app to version 4.42.0, and this time, it’s more than just bug fixes. The app includes a new service interface, introduces support for the new Model Y, and, for the first time, includes some code for the Robotaxi coming later this year.
This update was released for iOS and should be available on Android within a few days.
Refreshed Model Y 3D Model
First up in the update is the introduction of the 3D model for the refreshed Model Y. Interestingly, while we all know it as Juniper, the file code name inside the update lists the vehicle as “Bayberry.” The Bayberry name was introduced in Tesla app update 4.41.5. Tesla’s internal code names sometimes change as the vehicle evolves - and we’ll continue to refer to it as the refreshed or new Model Y for ease of understanding.

As usual with Tesla’s 3D models in the app, there’s a lot of detail, although it’s not easy to see since you can pinch and zoom the model in the app. The 3D models used in the app are actually the same models that Tesla uses in the vehicle, although sometimes they include different lighting effects, but they’re all highly detailed.
Robotaxi API
Tesla has added a new endpoint in their app for Robotaxi - and it’s the very first Robotaxi or Cybercab-related item we’ve seen in the app. With the Robotaxi fleet launching in June, according to Tesla, it looks like they’re now adding support to the Tesla app.
What the Robotaxi interface is supposed to look like in the future.
Not a Tesla App
The new app API is called “rides_feedback_upload,” which seems pretty explanatory. Tesla will need to gather a lot of information on ride quality and all the little things in between. What better way than to get feedback directly from users?
While Tesla previously released prototype images of what the Robotaxi app will look like, the introduction of this API into the Tesla app leads us to believe that Tesla will utilize the current app for Robotaxi use.
Updated Service Interface
The Updated Service Panel in the Tesla App
Not a Tesla App
Tesla has released an updated UI for the Tesla Service panel, and we have a ton of details on these changes. This new pane displays appointment details more prominently. If you have a service appointment scheduled, you’ll now see a lot more details on the main service screen. The app will now display:
Your current service status
Appointment date and time, which you can now tap on to add the event to your calendar
Address and hours of the service center. You can now also tap on the address to open up the location in your maps app
There’s also a new appointment details screen (the right portion of the image). This screen displays additional details that were previously unavailable, such as your transport type. The app will display whether you’ll get a loaner vehicle, demo vehicle, or something else.
There are a ton of user experience (UX) improvements in this update regarding service, including clearer language, improved UI fixes to images, and more.
Tesla has been making a lot of positive updates to the Service-related sections of the app lately, and we’re happy to see these coming rapid-fire. Tesla Service is now easier to use and understand. In the previous app update, Tesla also added the ability to pull down to update the service screens.
