M mom never drove, and my dad got to a point where he couldn't pass the eye exam and couldn't renew his license. I think he was kind of relieved. His driving in his later years was truly dangerous. We had to stop my mother in law from driving after her 3rd accident within 5 years put her in the hospital and a rehabilitative facility for several weeks. We convinced her to table driving for the winter. When spring came, she agreed to go to one of those clinics that assess your cognitive and physical ability to determine if you can safely drive. She didn't do well at all. She was not happy about it, but recognized that she shouldn't be driving. This was about 5 years ago. She's okay about now, but that was a tough several months as she got used to being without a car. It is truly a kick in the pants for the elder. Everyone is different, though, so it's hard to know when to step in. My mom's 90 year old neighbor still drives! Not much, but she does.
