My dad just lost his license at 75. My mother can't drive and has a mental disability which would hinder her. There is no ride progam in their area. I live 3000 miles away. I expect, if I don't change my life and move close to them, they will not survive very long in isolation. They are not too open about taking the bus. I am glad that my father will not be involved in an accident, but sad, because I know this will be the start of a downward spiral.
I do think there is a lot of cavalier type of thinking by some younger people on this post. I one time had two young men play chicken with me as I drove home from work. They came into my lane trying to cause a head-on collision with me. I was tired but my reaction was good. They just laughed. Lots of younger drivers are very rude.
We should have better public transport and support services for people. I myself would like to live in a city such as San Francisco or Toronto when I get older. They have good public transit.
One more thought on this... the people writing papers on the subject and coming off as know it alls, cannot write very well.
