Let me preface by saying that I'm an adamant Tesla supporter to my family, friends, and everyone that I talk to. I've been driving the X for 4 months now. I have a 21-year accident-free driving record. Last night on a return trip home with my family, my X 17.17.4 decided to try to ruin my driving record. I had AP2 engaged, hand lightly on wheel as always. The CA-99 freeway was very straight at that point, so I was in relax mode even with cars everywhere being a holiday weekend. Lane markers were clearly marked. Autosteer suddenly veered to the right lane as if it was doing a lane change right into a car next to mine. Reflex kicked in and I was able to jerk it back, but not without a violent swerve back and forth at 80mph. I'd understand if it was curvy, but this section was so straight! Overhead signs read, "Report Drunk Drivers. Call 911." I'm fairly certain that a few 911 calls were made reporting a drunken white Tesla X. I drove the rest of the way myself, not trusting AP anymore after that, not with my family on board. I've had close calls in the past in ICE cars, perhaps once a year if that, just part of the driving experience. In the past 4 months though, I've had at least a monthly scare. The latest incident had me swearing never to use AP until it improves significantly, until it reaches the stated yearly scare and not monthly scare. I just have to ask, is there anyone else not using AP at all? Don't get me wrong, I love driving my X and would buy it again in a heartbeat. I'm just curious if there's anyone else who completely lost trust in AP to do any of the driving.
