I think that’s a regional dependant one in terms of which should be prioritized. There a lot of factors that could lean on way or another.

For example, while Taxis drive around empty, car shares sit around empty. That’s a geometry problem that will be different city to city.

Also, car shares only allow people who can drive (and their passengers) to travel. Taxis can take anyone.

It’s a process, not a problem. Based on analogous estimates, that process takes about 20 years.

Infrastructure isn’t a quick fix either, so the physical and mental domains can progress at the same time.
