I think this is already true though for highway driving. Highways are long and tiring, and the surroundings model is easy to get right, so computers have an advantage. Most manufacturers offer a usable cruise control which is safe and can probably be active 90% of the time spent on highways. I often switch it on in my 3yo Hyundai as an extra safety measure in case the car in front of me unexpectedly brakes while I‘m not looking there. Add to that a lane keeping assistant and lane change assistant, and you don‘t need to do much. Except for when the radar doesn’t see an obstacle in front of you, eg because the car in front of you just changed lanes. That needs to be looked out for.
