@glemon I understand the sentiment, but the GM system is much more restrictive than Autopilot other systems that have bad reputations. You need to be paying attention to the road, it only works on mapped roads, and it has a very good indicator for whether or not it's activated. It was also the most complicated system to defeat when an org (IIRC Consumer Reports) saw what it took to activate a system and abscond to the back seat.
Calling a system Full Self Driving full self driving? And not putting restrictions on where you can use it, or monitoring the driver? That's when you get the cases of people falling asleep when they shouldn't.
I'd love to try Supercruise. As someone that has frequent all-day highway stints, this would be helpful and reduce driver fatigue.
