I dunno man. Adaptive cruise control with "stop and go" functionally is pretty fucking nice when you are in traffic. Just because something is "muscle memory" doesn't mean it is zero cost. Adaptive cruise control really makes stop & go a hell of a lot nicer to drive in 'cause you aren't constantly shuffling between two pedals.

As others have stated, it makes you quite a bit less irritable when the drive is over. That shit wears you out.

Next time you rent a car, get one with adaptive cruise control and give it a try. It is very handy!
