This will be interesting. As an aging nondriver living in Yokohama, I’ve been both hoping that self-driving cars become available here before I develop mobility issues and wondering how feasible they will be. Since I don’t drive, I don’t have a sense of what the roads here are like from the vehicle’s perspective. But many of the streets, including in the neighborhood where I live [1], are narrow, have no sidewalks, and are shared by cars, bicyclists, and pedestrians. Very different from, say, Phoenix.
