Most people that I know who have that cWe rented a VW a couple years ago that had adaptive cruise control, lane assist, and some other things. I really liked it.
I'd like to try a Cadillac with Super Cruise.
It's like anything though. I've gotten spoiled from having a backup camera. I used to be able to back up to my trailer and easily get within a couple of inches from the ball. The camera in my company truck has failed, today it must have taken me about 20 tries to get it right. It was fully loaded so "adjusting" by hand wasn't going to happen.
