My father was a horrible driver. I couldn't stand it anymore, so I contatced the DMV and asked them how I could get him off the road. I filled out a report and they sent inquiries to his eye doctor and his family physician who both said he should NOT be driving. The DMV had him retake his driver test which he failed and they finally revoked his driving priviledge. Remember it is a priviledge, not a right. He was furious with me, but finally agreed that it was better that he shouldn't drive anymore because he kept having fender benders and couldn't afford the repairs anymore.
