It isn't useless. Like cruise control, you don't need full automation to make driving more comfortable. Hands-off level 2 systems are great for long distance travel. I turn them off when I'm navigating situations that require high levels of decision making, however, e.g. driving through a crowded parking garage.

I suppose that comfort is an individual thing - having to sit in place, staring ahead, watching the road, with nothing to do, sounds to me like a kind of torture. I rarely use cruise control; operating the vehicle is what keeps me engaged enough in the drive that my mind doesn't wander. But cruise control is obviously popular, so there are clearly many people who experience driving differently.
