I found it useful twice so far. Once coming over a hill at night I was blinded by oncoming headlights. I could see the right side of the lane, but not the left. Same the other day driving into direct low winter sun. Had my visor down and sunglasses on but still couldn't see. Both times the car was like, "I got this, don't worry". So yes, I keep my hands on the wheel and let the car do it's thing, but I always have the ability to push the wheel where I want, and having that little extra layer of support isn't bad.There are times when you may be distracted for a split SE ond and it could save you. I have found it drives around kerb mounted parked cars very well, it is also easy to swerve off course while adjusting a setting, sometimes it takes longer than you think. Very useful on medium to long drives.
