Hi thank you for allowing me on to this group. Mu dad is 78 and has been diagnosed with dementia. He is still driving and refuses to accept he is no longer a safe driver. He carries his keys round with him by day and puts them under his pillow at night. My mum is unable to access the car to disable anything to stop him driving. He gets angry if anybody tells him he shouldn't be driving and goes in to rage. We are at a loss ad to what to do . He is at late stage 2 dementia
