Good. I sure hope only a small fraction of the population will be able to manually drive their car in the future. It would save lives, time, and money for everyone if the bulk of the idiots were unable to manually drive their car.
I'll give you "lives" and "money," but not necessarily time.
I live in a place where self-driving vehicles can be spotted fairly regularly. Once a week or so. You can tell by the special license plates. They are always very ponderous, careful drivers. It's fascinating to see them gently slow to a stop for a red light, then take off like a jackrabbit when it turns green.
Perhaps as the technology matures, they'll start to keep pace with traffic better.
I'm actually looking forward to self-driving cars. It's all the personal time benefits of mass transit (book reading, meditating, general mental health), without worrying about accidentally sitting in someone else's pee.
It would have to be a child being killed.
