Tesla has recently launched Full Self-Driving (FSD) v14.3.1, with software version 2026.2.9.7, building upon the major architectural changes introduced just over a week ago. This targeted point release aims to enhance the user experience, with critical refinements noted by early adopters.
One of the most significant updates in v14.3.1 is the enhanced parking interface. Users can now tap on a small arrow within the parking UI to access parking options directly, streamlining the process for drivers utilizing FSD for end-of-trip maneuvers. This improvement complements the broader enhancements introduced in v14.3, such as improved parking spot selection and a new “P” icon pin on the map.
The core of the v14.3 branch features a ground-up rewrite of the AI compiler and runtime using MLIR, resulting in a 20% faster reaction time according to Tesla. Drivers testing the software on highways have reported positive performance, with the update addressing a long-standing issue of phantom lane changes. The car now consistently initiates lane changes to the right-hand lane 2.5 miles before an exit, minimizing last-minute lane scrambling.
While the software has been praised for its human-like acceleration and deceleration, some users have noted sensitivity in complex urban environments. However, overall feedback from early testers indicates that v14.3.1 is the most stable and confident version of FSD released to date.
Early adopters have expressed satisfaction with the polished feel of v14.3.1, with many believing it is ready for wide release. The update has been commended for its improved highway performance, with the Mad Max mode feeling slightly more refined. Despite some remaining challenges in urban settings, the general consensus is that v14.3.1 represents a significant advancement in FSD technology.
In conclusion, Tesla’s rollout of FSD v14.3.1 showcases the company’s commitment to continuous improvement and innovation in autonomous driving technology. With enhanced parking features, improved highway performance, and overall stability, this latest software update demonstrates Tesla’s dedication to providing a superior driving experience for its customers.
