"It is a foolish man who believes that he possesses all of the answers until he is absolutely certain that he has heard all of the questions."
Watch the ads on tv for the components of driverless cars. They show people being distracted and the car taking over for them. Back up without looking and something or someone is in the way? The car stops. Not watching the road and someone or something is in front of you? The car stops. Goofing off and your car starts to drift into another lane? The car steers you back. And more and more cars come with self parking abilities built in. And don't forget GPS systems, WI-FI and satellite and smart cell phone tech already built in.
