I really want this to be controllable without letting go of the steering wheel. By modern I mean with a "max" mode like pretty much every new European car. I love the max speed mode, where you set the limiter to your preferred speed and then just keep a safe distance to the other cars. When the road is clear you hit the pedal and it accelerates smoothly up to the limiter speed. Press through the pedal resistance to go over for some reason. It's such a relaxing way to drive - you pretty much never have to look at the speed indicator and you never get fines. And before you say it: I don't trust AP and won't pay for it.
