Access to a car is everything in the U.S. My father began (illegally) driving at the age of thirteen. He helped to feed his family during the Great Depression by working for a local grocer delivering groceries in a pickup truck specially rigged for him. The day he became incapacitated by a stroke and too old to drive anymore, he handed me his car keys, and never sat behind the wheel of a car again. He was devastated by it, but knew the potential consequences of continuing to drive.
A 93 year old woman..that says it all right there....
This is California. They regularly renew licenses for the aged for long terms. My 99 year old mother gave up driving at 98 in 2012, but her license was good until 2015.
When questioned, she defensively claimed that she had “lots of friends” who were driving at 106.
