Back when I owned a taxi I used to do what are called desegration routes. I took little black kids who had a school across the street to a white school out in the county. I usually had to get them there about 7:47 am and it was about a 20-minute ride. So I usually didn't get up until about 7.
One time I went to a 7-11 to get some pastries and milk and probably some of those cheap cigars I used to smoke. It was drizzling a bit.
As I got into my car I noticed an old man, with a small plastic bag in his hand, walking in the rain. I knew what was going on: he had walked to the convenience store to get something to eat and was walking home in the rain. He had to live maybe one or two blocks away
I pulled up next to him and told him I would give him a ride, no charge. He got into the car. They always got into the car.
I guess he was about 75. He told me, in a calm voice, that he remembered his address but could not remember how to get to his house, even though he had lived there 30 years. So he gave me his address and I took him home. He lived two blocks away.
No self-driving taxi, robot, is going to look at old man walking in the rain and realize he was in trouble. But a human could.
That was not the only time I did such things. Once I got some gas and the attendent pointed to an old lady on the street and said he believed she was in trouble. I told her I would take her home, no charge.
She told me her address and I realized she was walking in the opposite direction.
She lived about seven blocks away, and I took her home. She insisted on paying me and even let me in her house (this was very common). She gave me, if I remember correctly, a quarter, which amused me. Apparently she still thought it was 1935.
These things are why there will never be self-driving taxis. They can't put a wheelchair in the trunk and help an old lady with a bruised hip up three flights of stairs and carry groceries inside or tell when someone needs helps just by looking at them.
By the way, such things as this happened to me a hundred times.
