The city with self-driving cars will economically outperform the city with human-driven gas cars.

Just like America economically outperforms Europe. The best and brightest from Europe/cities with manual human drivers will leave their dying cities behind and move to the futuristic, inspiring, and highly-compensating self-driving car city/America.

Europeans are upset that America is getting away with treating the underprivileged so poorly, yet America constantly outperforms Europe $-wise. And yes, everything in life is about $.
