Yeah don’t know how well that works in practice. Either I’m engaged and driving or I’m not. Letting the car drive while I continue to pay attention and somehow anticipate with superior reaction time that the car is going to make a mistake seems like more stress than it is worth. My current car has lane keep assist, which is helpful, but if I’m going to give full control of the car to the computer, then I don’t think I can/want to be on standby. Seems like more stress than it is worth.
