Update 2026.20.10 (FSD 14.3.5) - Release Notes

Full Self-Driving (Supervised) v14.3.5 includes:

- Upgraded the Reinforcement Learning (RL) stage of training the FSD neural network, resulting in improvements in a wide variety of driving scenarios.

- Upgraded the neural network vision encoder, improving understanding in rare and low-visibility scenarios, strengthening 3D geometry understanding, and expanding traffic sign understanding.

- Rewrote the AI compiler and runtime from the ground up with MLIR, resulting in 20% faster reaction time and improving model iteration speed.

- Mitigated unnecessary lane biasing and minor tailgating behaviors.

- Increased decisiveness of parking spot selection and maneuvering.

- Improved parking location pin prediction, now shown on a map with a P icon.

- Enhanced response to emergency vehicles, school buses, right-of-way violators, and other rare vehicles.

- Improved handling of small animals by focusing RL training on harder examples and adding rewards for better proactive safety.

- Improved traffic light handling at complex intersections with compound lights, curved roads, and yellow light stopping — driven by training on hard RL examples sourced from the Tesla fleet.

- Improved handling for rare and unusual objects extending, hanging, or leaning into the vehicle path by sourcing infrequent events from the fleet.

- Improved handling of temporary system degradations by maintaining control and automatically recovering without driver intervention, reducing unnecessary disengagements.

- Improved driver monitoring system sensitivity with better eye gaze tracking, eye wear handling, and higher accuracy in variable lighting conditions.

- Help Tesla improve Self-Driving by selecting an intervention reason on the main screen after taking over.

- You can now see distance traveled in FSD (Supervised) without an intervention. The Self-Driving App will also show your longest intervention-free streak.

- Parking options now display on the map when arriving at your destination.

Upcoming Improvements:

- Expand reasoning to all behaviors beyond destination handling.

- Add pothole avoidance.

Check your Owner's Manual for additional guidance regarding the second row child safety seat installation.

- You can now select an arrival option such as Carpark, Indoor Carpark, Street, Driveway, and Pull Over for Robotaxi-style drop offs.

- Your preferences for arrival options and preferred parking positions are persisted for each destination.

- Our reasoning model will assess the suitable options for your destination and pick an intuitive default.

- The navigation pin will be adjusted based on the selected Arrival Option.

FSD (Supervised) will now determine the appropriate speed based on a mix of driver profile, speed limit, and surrounding traffic.

- Driver profile now has a stronger impact on behavior. The more assertive the profile, the higher the max speed.

- Right scroll-wheel up/down now adjusts Speed Profile setting rather than your precise max speed offset selection in mph or km/h.

- Introduced new Speed Profile SLOTH, which comes with lower speeds & more conservative lane selection than CHILL.

Navigation now shows which lanes to take to follow your route. This feature requires Online Routing and Maps version 2026.20 or later. To enable, go to Controls > Navigation > Online Routing.

You can now send navigation destinations directly to your Tesla. To send from the Mobile App, go to Location > Navigate, add a destination, and tap Send to Car. Requires Mobile App version 4.57.0 or later.

To send from NAVER Maps or TMAP, add a destination and go to Share > Tesla. To send from KakaoMap, add a destination and go to Share > Share Address > Tesla.

- You can now view your Self-Driving stats under Controls > Self-Driving.

- Start Self-Driving with a tap of the touchscreen from Park, or any time during your drive.

- Adjust settings like the Speed Profile and Arrival Options directly from the Self-Driving visualization on the center display.

Maps now show weather data, including different types of precipitation like rain and snow. You can also view the past hour of weather data to see how conditions have been changing along your route. This feature requires Premium Connectivity. To view, tap the weather icon on the map.

You can now tap on points of interest on the map to explore destinations or begin navigation.

Brake Confirm for the Start Self-Driving button is now defaulted off. When disabled, Start Self-Driving will not require you to press and release the brake to confirm engagement.

You can enable Brake Confirm in Self-Driving > Brake Confirm.

Tesla will now display whether a vehicle has FSD enabled in the Tesla app. In addition, the app will now also display the blue FSD path and even the rainbow road easter egg if it’s enabled in the vehicle.

This requires Tesla app update 4.58.5 or higher and vehicle update 2026.20.6.1 or higher.

With Tesla’s recent addition of license plate customization, they also added a shortcut for it under Controls > Software.

With this update, Tesla tweaked the icon slightly by adding a license plate frame around the license plate image being used for a cleaner look.

In update 2026.20, Tesla started encrypting Dashcam footage. This came at the same time as Tesla expanded recent video footage from 1 hour to up to 24 hours under certain requirements.

Encrypting the videos is an important privacy change, since if your USB drive is pulled from your vehicle, thieves can now have access to up to 24 hours of your driving, potentially revealing your workplace, home, and other important locations.

With this update, Tesla also added a button to the Dashcam Viewer that lets owners easily decrypt a specific clip, making it easier to see the footage if they mount the USB drive to their computer.

Tesla also introduced a tool that lets you decrypt any videos on your computer, as long as you log in to your Tesla account to prove that you own the video footage.

Tesla’s navigation now supports bus lanes, helping drivers be more aware of which lanes they can use.

This is even more important for FSD, so the vehicle can know which lanes are appropriate to drive in without having to read or potentially miss signs.

Forward Camera View Cleaning Panel

A new Forward Camera View Cleaning panel is available under Driver Assist to support cleaning the surface of the windshield in front of the cameras. The panel displays a live camera stream with the ability to zoom into the camera stream.

Models: Model 3, Model Y, Model S (2021+), Model X (2021+) with DAS AI4 and Cybertruck

Drive Unit Panel Update - Signal Chart Popups (Service Mode Plus)

The Drive Unit panel now supports interactive signal chart popups. Signals with a chart icon can be tapped to open a draggable, resizable popup window for real-time signal monitoring.

Models: Model 3, Model Y, Model S (2021+), Model X (2021+), Cybertruck
