Especially if someone is in the car with them to direct them. My FIL has pretty bad short-term memory loss and also hallucinations. I worry he shouldn't drive (MIL is recovering from an injury), but MIL got annoyed by me offering to arrange transportation for them and said they were safe. Opinions?
Oh how our elders hate to give up their cars. My very elderly parents were the same way, I now that I look back, I think it was my Mom who was insisting that my Dad drive her places... she was in denial of my Dad's age related declines. I also tried to do what you did, arrange other transportation, but that went over like a lead balloon.
