Agreed here too. Pretty much all my experiences with these kinds of features have been poor. I turned off the emergency breaking on our Tesla after it slammed on the brakes for no reason on the highway a couple of times. Could easily cause someone to rear-end you. I also recall a Kia I rented once that had automatic lane keep assist and blind spot warnings. The blind spot warning was so sensitive that it would loudly beep at you if there was another vehicle anywhere near you in the other lane when you put your turn signal on. Not helpful, and quite distracting. The lane keep assist was worse, because the way it pulled on the wheel any time you approached the edge of a lane (which it turns out you do often in the course of regular driving for all kinds of reasons - another car crowding you, giving room to a cyclist, taking a smoother line through a corner, etc.) felt very much like losing traction. It was quite disconcerting, and I could see it causing someone to overcorrect and lose control. And to paraphrase Matt Farah, if you need assistance to keep in your lane, you shouldn't be driving.

All that said, I do like the autosteer on the Tesla, with the caveat that you need to treat it like cruise control, NOT like "autopilot". And I'll pretty much only use it on divided highways. In other situations its insistence in sticking to the dead center of the lane can be disconcerting at times (like the ones I listed above!)
