I've been driving my Model Y (June 2021 build) for roughly seven weeks now and I'm finding the auto pilot nearly unusable. The braking is so overly aggressive that it basically catapults me forward constantly. It will go from 65 down to 40 suddenly and simply does not ease into braking whatsoever while driving on the freeway. It's an uncomfortable driving experience and it's dangerous for possible rear end accidents. I've tried switching the trailing distance of the cars in front of me from two car lengths all the way up to seven and it drives no differently. I had a Model 3 for about 3 years, that had EAP, and the auto pilot was NEVER this bad. Is this due to the switch from radar to Tesla Vision? Might this be fixed with a future software update, or is this just how it is? I'm curious to hear how others have found the autopilot on recent builds with Tesla Vision.
