I agree. There's also one UK owner who's reasonably well known (until he gets banned for one reason or another) who works in a hospital and happily posts videos of his MX driving the kids to school on AP as if its some kind of badge of honour with the usual commentary being "it couldn't navigate this junction on the previous version" or worse "it made it to the school gates today avoding the parked cars dropping kids off"...
I liken some peoples use of AP to that of drink drivers of old. They work on the premise if they've not yet had an accident using it the way they do then its safe. My uncle thought like that until one day in the earlly 80's when he didn't anymore, I'm glad I wasn't in a baby seat in the back at the time.
As for positioning in the lane, ot often seems to know according tot he dash exactly where it is in relationship to the road but still hugs one side or the other more than I'd like. I'd actually like the ability to trim it left or right of the lane somehow although I imagine Tesla in their wisdom don't feel thats important. I think it would make it a much better system if they took into account the aggregate of drivers preferences given the view of the road. Slap bang in the middle all the time isn't how good drivers drive
