"Over 90% of all road fatalities occur in low and middle-income countries, which have less than half of the world’s vehicles." Not really relevant statistical baseline here. Self driving cars aren't going to help in areas where people can't afford them.

Not in the near future. Think 100+ years. I can totally imagine owning a human driven car to be the luxury choice.

Seems like we're proportionally better at the seemingly more complex task of driving, than we are at maintaining our health. Heart disease in the U.S alone apparently kills about as much as half the number of worldwide car related fatalities each year.
