From my sad experiences, there's a small time window between a person losing her license and being unable to getting in and out of a car on her own to handle, say, grocery shopping.
And when more people can't drive, that also means they may be helpless when the autonomous vehicle gets stuck, physically or algorithmically--especially if the engineering geniuses believe they should do away with the steering wheels.
I just placed a washing machine transmission in my car during my work break so I can finish working on it at home. If I was calling a robo-taxi after work to load that transmission up, I would miss the precise "low traffic" window we have here and my commute would be > 25% longer. Again, no thanks. Again, scenarios the geniuses are unaware of.
I wonder what I will encounter tomorrow.
