On Sunday, Tesla started rolling out Full Self-Driving (Supervised) V12.3.6, the latest version of its FSD software. This update includes the highly anticipated new Autopark and High Fidelity Park Assist feature for additional vehicles. FSD v12.3.6 replaces v12.3.5 which had only been rolled out to a small portion of the fleet.
The new Autopark (tap to park) and High Fidelity Park Assist features are now available for vehicles with ultrasonic sensors (USS). Since October 2022, all Model 3 and Model Y vehicles no longer include ultrasonic sensors, instead relying solely on Tesla Vision to provide Autopilot, Park Assist, and Autopark features. However, the vision-based Autopark has been limited to the U.S. and Canada so far.
New Autopark
When driving at low speed, the new Autopark highlights potential parking spaces allowing the driver to pick their preferred spot. Tesla vehicles with ultrasonic sensors (USS) can now take advantage of the new Autopark feature, which is a significant improvement over the previous iteration.
Although the new Autopark feature is expanding to vehicles with USS, it appears to still be geographically limited to the U.S. and Canada. We expect Tesla to continue the feedback loop and release the feature in Europe and other regions in a future update.
Vehicles without USS outside of North America have never had Autopark of any form since they don’t support the older Autopark version that relies on USS and have yet to receive this latest revision of the feature.
For vehicles with the Intel-based infotainment unit, the visuals will look like the video below, where it doesn’t display a 3D environment of the vehicle’s surroundings. Instead, the visualization just highlights parking spaces available. However, the limitation for Intel vehicles is just in the visualization itself, the vehicle is just as aware of its surroundings as vehicles that display 3D renderings of objects on the screen.
With Tesla update 2024.3.25 (FSD v12.3.6), Tesla is also releasing High Fidelity Park Assist features to vehicles with ultrasonic sensors. However, as initially suspected, it’s limited to vehicles with the most recent infotainment processor that includes the Ryzen chip (MCU 3). Unfortunately, Intel Atom based vehicles don’t include the 3D visuals of High Fidelity Park Assist.
The feature provides drivers with a 360-degree 3D reconstruction of their vehicles’ surroundings while parking while traveling at low speeds. It even accurately displays lane markers in parking lots helping drivers visualize the environment around them when parking. The feature was added as a late addition to Tesla’s 2023 holiday update. However, at the time, it was limited to vehicles without ultrasonic sensors (USS).
For vehicles that have ultrasonic sensors, users will have a choice to either continue using their vehicle with USS sensors that display exact distances to objects or use the new High Fidelity Park Assist feature and forego the display of distances.
We were hoping that when Tesla finally released HiFi Park Assist to vehicles with USS, it would merge the two features and display the updated visuals with distance measurements, however, that is not the case in this update.
For owners with USS, the new Park Assist option is located under Controls > Autopilot and allows you to choose between “Standard” or “Tesla Vision.” Tesla Vision being the new HiFi Park Assist and Standard representing the USS version with arcs and measurements.
Tesla’s director of Autopilot, Ashok Elluswamy had previously set expectations and stated that HiFi Park Assist would “eventually” go to vehicles with ultrasonic sensors back in December 2023. The new Park Assist feature is available in various regions around the world, including North America and most of Europe.
Tesla continues to double down on vision and Musk revealed that it's becoming “very clear that the vision-based approach with end-to-end neural networks is the right solution for scalable autonomy”.
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.
