Yea but now electric scooter are all the rage and he was basically right (execution was wrong). Cities are even thinking about restructuring roadways to accommodate them (and more bikes).
Electric scooters are barely a blip in a city's overall transportation scheme. The biggest regulations going on is how to keep them from blocking the sidewalk.
Even restructuring a citys roadways for bicycles--a long-term, proven good technology--has been incredibly slow going. And this with something governments are actively trying to improve.
It will be decades until there is substantial enough change that self driving cars are viable as described in the great-grand-parent. And that's if it moves quickly.
