Want to see Tesla’s Full Self-Driving (FSD) AI system become a track driver? You’re on the right page. The latest Tesla FSD (Supervised) version 14.2.1 is proving to be the best installment of the AI self-driving software yet.
A Tesla owner and influencer, Zack (@BLKMDL3) took his HW4 Tesla Model Y to a difficult mountainous road known among the Californians as ‘The Snake’ (Mullholand Highway, California). The name suggests its curviness and the level of difficulty while driving.
Taking a car on this difficult track, which is driving itself, is an act of courage. The Snake is infamous for its racing track-level hairpin turns and more or less than 30 curves.
With the help of the map screenshot on the right of the image above, you can grasp the level of driving difficulty of The Snake. Tesla FSD v14.2.1 successfully drove through this hard-to-navigate hilly road on its own (under human supervision).
These type of curvy tracks are a challenge even for average human drivers. However, Tesla FSD v14 completed it on the first attempt. The Snake Highway goes through the Santa Monica Mountains around Calabasas and Malibu, California.
Such hairpin turns can be witnessed at race tracks like Laguna Seca and driven by professional drivers using modified Tesla vehicles.
FSD v14.2.1 driving on these roads is not less than magnificent. With each new update, Tesla FSD is getting better.
Recently, Tesla has introduced a free 30-day trial for FSD v14.2 for Tesla owners in North America. This year’s Holiday Season is a great chance to experience Tesla’s Full Self-Driving system.
V14 is great, but V13 did do Pikes Peak, twice. One was totally dark!https://t.co/0GsK40zQji
