Whatever Tesla is offering, it's not even remotely full self driving. It can't handle much beyond a highway on a sunny day, and even then, they have an unfortunate habit of crashing into stopped emergency vehicles.

Reduction of total cars on the road, in favor of competent mass transit, would do much more to actually reduce suffering. But Musk wants money, not improved quality of life for those who can't afford Teslas. This isn't some rinkydink charity, it's a fat slice of a trillion dollar industry.
