I predict that in 2031 no major car company will offer self driving technology (besides emergency auto breaking) in personal cars. Even Tesla will stop offering what it has now. Reason: too many lawsuits.
By 2031 most new cars will have lane keeping, emergency braking, traffic light & sign sensing. And likely more. Almost all cars will drive hands-off steering wheel on the highways. By 2031 a big proportion of new cars will be electric.
