Replacing all cars with self driving cars is a lot more expensive than just adding proper bike infrastructure.
In fact, building proper bike lanes doesn't mean you can't have self driving cars too. It just means the people who didn't spend tons of money for a self driving car are less likely to hit the cyclists.
But anywhere you could be safely traveling 50mph+ is probably not the type of road I’m advocating building bike lanes on…
Why do we have one?
But they’re both forms of urban transportation that share the same infrastructure.
