After a skim of this sub-thread I'm surprised no one mentions that it might be a benefit that as autonomous-car driving tech spreads around world (presumably with SF/SV being the epicentre), countries which are poorly equipped for autonomous cars start to find the momentum to overhaul their road network and driving education system.

Having been to several countries in Asia, it would be no bad thing to have a stepwise reform in how driving is done in these countries - think of the number of accidents that would be reduced.
