I’m still a couple decades off from “senior”, but I have already reached a point where most day to day driving feels like a chore. If/When Waymo finally arrives in my smallish Bay Area city I can see myself using it a quite a bit. Hopefully self-driving cars are ubiquitous by the time I reach “shouldn’t be driving” age.

When I lived in Charleston the transit system had both subsidized ride share and ADA-compliant ride services (literally a government taxi service) for seniors and the disabled. So it certainly can be done.
