Tesla has begun rolling out the Full Self-Driving (Supervised) v14.3.7 version to its users as part of the 2026.21.6 software package. The new update brings performance improvements across a wide range of areas, from the AI ​​model to driver monitoring systems.

This version, which has begun to be distributed, specifically targets model training, surrounding perception capabilities, and reaction times to challenging traffic conditions. Tesla has implemented extensive technical changes to provide a more stable and reliable driving experience.

Technical Improvements and Driving Experience

Tesla has improved the system’s success in different driving scenarios by updating the Reinforcement Learning (RL) stage of the FSD neural network. With the update of the vision encoder, higher accuracy is aimed for in critical aspects such as understanding traffic signs and 3D geometry perception.

The AI ​​​​compiler and runtime infrastructure have been completely rewritten using MLIR. Thanks to this engineering change, the system’s reaction time has been accelerated by approximately 20 percent.

Significant improvements have also been made in lane usage and parking maneuvers. Unnecessary lane changes have been reduced, while parking space selection and maneuverability have been made more stable.

Thanks to the improved parking position prediction feature, suitable parking spots are now shown on the map with a P symbol. In addition, the maximum speed of the Actually Smart Summon feature has been increased to 13 kilometers per hour.

Security and Driver Monitoring Systems

The new version provides more proactive reactions to emergency vehicles, school buses, and other vehicles violating right-of-way. Safety-focused improvements, such as the detection of small animals and unusual objects, have been trained through challenging driving examples.

The system’s performance has been improved at critical points such as combined traffic lights, complex intersections, and yellow light stop decisions. System failures are minimized thanks to the automatic recovery feature in case of discontinuous system errors, eliminating the need for driver intervention.

The driver monitoring system has also been updated with improved eye-tracking accuracy. The system operates more stably in challenging conditions such as the use of glasses or variable lighting.

Users can specify the reason for intervention via the main screen when the FSD (Flight Safety System) is deactivated. Additionally, the application reports the total distance traveled by the driver without intervention and the longest uninterrupted driving series.

Tesla announced the unification of Actually Smart Summon, FSD, and Robotaxi models. Upcoming updates include pothole avoidance assistance and an expansion of the Smart Drive system.

How far do you think the safety improvements Tesla is focusing on with this new version will advance the autonomous driving experience?
