After my mother had several small strokes her cognitive abilities deteriorated along with her ability to drive. We tried to get her Dr. to declare her unfit to drive so we could get her license revoked but he declined. We found her car in the garage one day with the entire drivers side wiped out from front to back, she claimed to know nothing about how it happened. Got her Dr. to finally restrict her driving, had the car repaired and took it away from her after it came out of the body shop. She wasn't happy about it but finally agreed she shouldn't drive anymore and I sold the car, glad she didn't kill anybody.
