Description

Join us for a detailed, no-filter review of Tesla FSD 14.2.1 on a challenging road trip to New York City!

This version of Full Self-Driving encountered several critical and alarming issues. See the moment FSD attempts a dangerous high-speed pass on the right of a truck and find out why we had a disengagement. We also highlight major problems with speed management, including driving 68 mph in a 55 zone and ignoring a 40 mph work zone.

The navigation performance also struggled: FSD missed a crucial highway exit, ignored "left-turn only" lane signs, and ultimately failed to find a working charger in Brooklyn, leading to a frustrating detour.

Watch to see every anomaly, including poor lane discipline and a false pull-over for a phantom ambulance siren. Is FSD 14.2.1 a step up or a step back?
