Trust me they are nothing compared to the poor road conditions, lunatic drivers or dangerous weather you'll find in the rest of the world or even the USA.
Does anyone seriously believe that seld-driving cars are only a few years away?
So far I have only seen them working in nicely controlled environments (American suburbs or highways, nice weather, clear road markings, etc). And even then they drive slowly and awkwardly.
How will they handle the narrow roads in British towns, the unwritten right-of-way rules on Swiss mountain roads, the scooter avalanches of Vietnamese cities, the pot hole riddled streets of Russian cities, etc?
I think this is just an other case of Silicon Valley folks not realizing what's outside of their bubble.
