To barely scratch the surface here, mass transit helps solve congestion issues, something almost all car-centric cities suffer from. Forget the word public, I know that scares some people. We are talking about space and efficiency now. How would putting everyone back in cars help? Autonomous or not, tightly following or not, super syncronous (good luck with company interop and human drivers on that one) it's a lot of energy and space for 1-4 people, and we already know most city's road infra can't support everyone. You'll just be stuck in traffic autonomously instead of on a train moving more people more effectively.
