My AP1 is rock solid. I know what it can do, and I know what it can't do.
When on the Interstate, I'm much more relaxed with AP on with it off, but I don't hand the driving over to the car and zone out.
I don't turn my brain off, but I do relax and keep a light hand on the bottom of the wheel. That keeps the nags away, and it allows me to adjust quickly if AP loses a line and shifts towards or away from the other one.
I frequently glance at the instrument panel to make sure I know how well AP is seeing the road.
I watch the road, albeit more casually than when the car is not steering, because it doesn't see either road damage like potholes, or obstructions like cement blocks or stopped fire trucks.
I can't comment on AP2 because I haven't used it. But AP1 is perfectly safe if you understand its limits and don't try to exceed them.
