Last Thursday, I was headed home from San Francisco on 24 Eastbound. Went thought the Caldecott tunnels. Was in the right most lane of the right tunnel. A couple of hundred feet before the end of the tunnel, AutoPilot suddenly swerved right and hit the curb. I had my hand on the wheel and reacted quickly. Quick enough that the only damage was a curbed rim and a messed up section of my aero hubcap. This was on 2019.12.1.1. I forgot to hit the steering wheel button and say "Bug Report WTFU HAPPENED" The next morning I received 2019.12.1.2 and AutoPilot handled the same tunnel perfectly on Saturday. I love my car, but I try to keep at least one hand on the wheel 99% of the time.
