I installed 2022.8.2 yesterday, and the release notes claim that it improves autopilot performance in stop-and-go traffic by using more regen braking. I tried it this morning and the operation seemed much jerkier than before, both in decel and accel. A few times I had to tap the accelerator to get it moving when the lead car pulled away, but in other cases it would take off on its own - very inconsistent and unpredictable. On top of that, there were continual chimes and a couple of chirps that I could see no reason for. From this one experience, it certainly didn't feel like progress; I feel it was smoother before. My car is a 2021 with radar.
