I initially posted that autopilot seemed to be behaving about the same as it did in V8 on local roads (have yet to test it out on the highway), with the exception that it does a much better job of handling slowing down for red lights. This remains true, with the exception that it's now tried to kill me 3 times, on the same road that I drive to work several times per week. I got a recording on the dash cam of one time when it did it.
The first time, I attributed it to a car that was about to turn right onto the road possibly being a bit in my lane (although I didn't remember the car being in my lane), causing the autopilot to think it was going to avoid a collision. However, the next time it happened, I was just driving along the road going straight, without any other cars in the area, and without any reason for the car to try to take evasive maneuvers. There were no upcoming turns and the lines were perfectly clear without interruption. The final time, which I've attached video of, I was coming up to an area where cars can turn onto the road, but there weren't any cars in the way, there were cars ahead making things very easy to follow, and the road is very clearly marked ahead. The swerve occurs at around 33 seconds.
I've driven this road for years with autopilot and I can't remember a single time it's done anything like this. However, it's now done it 3 times on V9 autopilot. Unless Tesla has come up with a dangerous way to assure you're paying attention, I can't figure any reason that this would be happening.
