I've actually driven many thousands of miles with level 2 ADAS. There is no "not paying attention" in the system I'm using. If you even spend a few seconds too much gazing out the sides the system will beep at you and eventually pull over. If I take a few too many sips from my cup it'll beep at me and eventually pull over. I have to actively be shifting my gaze around out of the front, constantly being attentive to the cars to keep it in level 2. It's really not inhuman levels of constant vigilance, not anymore than actually driving the car regularly. I just don't have to actively be keeping the pedals just right to maintain the following distance myself and I don't have to constantly fight the wheel.
