My mother is 83 & she has not had a driver's licence for over a year. She is starting to drive again & because the police have not done anything to her (we've called them & they have warned her not to drive), she thinks its ok to do so. She will not listen to reason, will not voluntarily give up her keys. Where do we put the car? She won't sign the title, so we can't sell it. No family around to store it. She is a danger to herself & to others. Suggestions?
