Apologies if this has been covered elsewhere. I've read several good descriptions of AP and how it functions...including the Tesla manual, PapaFox's "a flight instructor teaches AP" as well as viewed Todd Burch's great video. I feel like I'm pretty well prepared. That said, I'm sure there are things that all of you with AP have learned since getting it. In preparing to pick up my second Model S this Saturday, I'd like to know from those of you who use AP a lot...what 2 or 3 things do you wish you had known from the very beginning about AP?
