This is a very difficult situation for family members. You are his child and this is the way he sees you. I am sure he thinks he knows best when it comes to his independence. However, there is a safety issue here, not only to himself, but a public safety issue. Maybe he would agree to not driving alone; is someone available to accompany him when he is out and about? You could ask his family doctor to disccuss the situation with him. This is sometimes helpful as opinions of the doctor are usually not seen as 'interference'. I never had to deal with this problem with my dad ... thank goodness; he drove his car until three days prior to his death. Very difficult as your dad probably feels he is losing control of his life; you mentioned he is living in an independent facility. He may be feeling a little angry at himself for aging and fearful of losing his independence, so he is determined not to give up his usual daily activities ... seen as stubborness.

Hope this is helpful to you.
