It`s definitively all about options ans alternatives. There is a bunch of research on this topic.
We also tested it with my grandma who never would have given up driving.
It was the free Taxi Option, that she soon called her chauffeur. Her own car was more and more forgotten in the garage as the chauffeur also helped with the bags at her cottage...
Everyone was Happy...
Now I continue work on automated cars;)
