You're probably right about comparative costs. But the problem of getting to an autonomous bus will remain a significant barrier to public transportation use.

You're probably right about comparative costs. But the problem of getting to an autonomous bus will remain a significant barrier to public transportation use. My neighborhood is close to the city center. Even so, bus service is very sparse, recently reduced to just twice a day. In addition walking to bus stops is long and difficult, or even impossible, for many elderly or disabled residents. I envision a Waymo-like car service transporting people to/from destinations or if it's more practical, a transit center. I concur car services wouldn't be the cheapest option but may well be the most effective.
