My house is on the side of a steep hill. If in a few years—I am now 67–I become unable to walk up that hill, the only way I will be able to go anywhere is by calling a taxi. (No one in my family here knows how to drive.) Because of demographic trends, there is a shortage of human taxi drivers now and that shortage is likely to get worse. If I do become significantly less mobile five or ten years from now, I will be able to keep living in my home only if self-driving taxis are available.
So for me, in that very likely scenario, self-driving cars would make my life better. In Japan, there are millions of people in similar situations to mine.
