My opinion on this doesn't matter much. I turn 47 in two months. I will be retired and, if I am fortunate, living a pedestrian's lifestyle by the time even half the cars on the road are self-driving. It's going to take a ton of work, only a small fraction of it technical, to make widespread driverless cars a practical reality. If I do need to use a car, I will always own my own, full stop. I don't care about the counter-arguments. I don't want to ride around in a vehicle that spends half its time as a sex den for extramarital affairs and hormonal teens.
