After driving a brand new Model S loaner with AP2 for over a 1,500 mile road trip with the family, I'm just personally glad to have my AP1 2016 Model S back for daily use, with its "limited" features. I don't care what anyone says... AP2 (even on recent firmware 2017.46.9) is NOT ready for primetime.
Heck, even when only using a feature that is common and functional on other cars from other manufactures, namely adaptive cruise control, was outright dangerous on the AP2 car. IMHO, I wouldn't even consider it viable "public betaware" in its current form on AP2. I've never driven a car from any manufacturer where the adaptive cruise control kept braking on the highway after incorrectly marking a car in another lane as being in my lane. And that happened multiple times, all on well marked roads in clear weather. WOW. Even using this feature in 5 MPH stop-and-go traffic wasn't worth the sudden harsh braking versus the more predictable and smoother AP1 behavior.
And forget steering with AP2. Its just not there yet versus AP1. Basically made all of my family car sick with repeated knee-jerking little adjustments. The only time AP2 was really usable, was when it was on very straight highway with no cars around. Otherwise, too much unexpected behavior with the family literally begging me to drive. And don't even mention the overly-aggressive and nauseating lane changes with AP2. Who are the idiots at Tesla who would approve this kind of driving behavior? Race car drivers?
So all-in-all, I'm perfectly content with my AP1 car, even if there are no new features going forward. Now I really understand and empathize with AP2 owners who are complaining and even downgrading to CPO AP1 cars. Ouch.
