Likewise. The only bizarre behavior I see is "looney tunes" style confusion where the road construction crews have left old lanes in place that steer into a wall or off the road. Humans mostly understand that these are lines lazy construction crews have left (although the debris fields near the barriers maybe tell a different story), but the Tesla vision model likes to try to follow them.

No clue. I had used it for maybe 10-100 of miles and didn't have any issues before this morning. The car's a bit dirty, maybe something's on the cameras?

Before this morning, I would be in exactly your shoes in terms of "this is pretty cool, I'm going to keep using it"
