That's a fair point, though usually the usefulness of cars and public transportation are inversely correlated. Starting with a good foundation for public transportation would reduce a lot the need for cars for commuting in the city.

That’s because you need to park personal cars. Car share solves that problem by keeping the cars on the road.

Last mile is always a challenge for public transit because the economies of scale don’t kick in at the necessary scale.

Self-driving car share is basically like having hundreds of four-person bus routes. Except they run on-demand.

That's something I didn't think about, thanks.
