I've had my Tesla Model 3 for about 2 months now. I've had mixed success with autopilot. It seems to work best when I'm driving on a highway where there is light traffic. If there is stop and go traffic, I find that it can over accelerate or over decelerate as the cars stop and go in front of me. Yesterday I was driving on a local road with 2 way traffic. The speed limit is 35 and a car made a left turn in front of me, Autopilot slowed down alarmingly fast, there was a car behind me and I was worried he might smash into me, but he didn't. The car making a turn had plenty of room, if I were driving without AP I might have slowed down slightly, but certainly not as hard as AP did. When I thought about it afterwards, I think the 6 car lengths space I had maybe was the reason for this. Should I set it to 2 or 3 when I'm driving on a road that is only 35 MPH?
