Full Self-Driving (Supervised) v14.3.7 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.

- Unified the model between Actually Smart Summon, FSD, and Robotaxi for more capable and reliable behavior.

- 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.

Under din övervakning kan total självkörningsförmåga (under uppsyn) köra din Tesla nästan var som helst. Den utgår från en parkerad position, gör filbyten, väljer förgreningar för att följa din navigeringsrutt, navigerar runt andra fordon och föremål, gör vänster- och högersvängar och parkerar vid din destination. Du, och alla du ger tillåtelse, måste vara extra uppmärksamma och försiktiga. Det gör inte ditt fordon autonomt. Behåll uppmärksamheten.

Total Självkörningsförmåga (under uppsyn) är aktiverad på ditt fordon. Använd funktionen genom att trycka på knappen Starta Självkörning i gränssnittet eller trycka en gång på höger rullningsknapp. Du kan inaktivera Total självkörningsförmåga (under uppsyn) i autopilotinställningarna.
