So I did some more driving today with this version, and highway autosteer is really nice. I also did some local road tests, and have a couple of videos to share. Sorry but no audio.
The first one is pretty amazing. The video starts with me turning onto a road and immediately engaging autopilot. It ends with me stopping at a light. I did not intervene in between at all:
The second is an instance of hill crest mis-handling, which some folks were looking for. Right around 26 seconds you can see me take over so I didn't run off the road. I think the fact that there was a side road at the top of the crest contributed. Possibly also the power line shadow, though I have not seen those causing many problems lately.
