I've tried it a few times an find it terrifying (takes exit lane when it sees a gap, jerks car from side to side, etc.), and because the steering wheel blocks the area where it's indicated I have to take my eyes off the road to find / see if I can get it to Assisted Cruse (which is very nice). I wish I could have it removed from the car, and that it was not the default setting. Very dangerous. Highly not recommended.
There is no such a thing as a self-driving car, and there never will be. Humans are terrible drivers (and getting worse), but still orders of magnitude better at interpreting real world driving situations than machines will ever be.
I am getting used to the duck and juke necessary to see what's behind the enormous A pillars. Had a couple of very close calls pulling out into oncoming traffic that was entirely blocked by driver's side A pillar, and about a half-dozen close calls from both. Haven't let the wife drive the car much until I can train her.
Other minor annoyances: the three bump entry dance: bump head getting in, bump again reaching all the way out to retrieve door, bump head again pulling door shut. It would be nice if the drivers seat stayed in the fully back and down position I have it in when I exit, but it goes back to the programed driving position if you do anything else first, like open one of the rear doors. First thing I do now when I open the driver's door is reach down and put the seat all the way down and back, again. Kinda defeats the auto-preference feature.
Would be kinda nice if: instead of the swag, how about giving Faraday pouches for the fobs, extra fob batteries, extra aero wedges and fasteners. ...
