Not sure about your car but the car I have with augmented cruise requires hands on wheel. Turns off otherwise. (Volvo XC90)

I agree that there are situations where what I do as a trained driver is different from augmented cruise.

A good example (or perhaps I'm wrong) is this: in a lane, car pulls into lane in front of me and between the car further ahead. Now I don't have enough space in between me and that new entrant. But instead of using brakes (unless eggregious), I bleed speed until I make space I want. Augmented cruise doesn't do that - it hits brakes.

So, from behind, I think it looks like I'm using my brakes a lot more than I am when on augmented cruise. And excessive brake use distracts the driver behind me.
