I am very concernced about a year ago my neighbour was diagnosed with Alzheimers Disease and after getting lost driving and not being able to find hiw way home the GP decided to inform the DVLA that he should not be driving. SO the DVLA ordered him to return his licence and he was not to drive. 1 of his sons about 5 months later sold his car as they feld he was a threat on the road. Once his car had gone he started taking his wifes car. I told him that he is not insureed and he wasnt beng fair on other road users if he had an accident. He just does not understand or get it he says hes ok hes been driving for years. this went on for a few months him drigin his wife car. At the weekend he tells me he has purchased a new car I told him with disgust he shouldnt be driving and again he doesnt get it. He is a menace on the road my neighbout told me that he was speeding aruond the smallest of bends and was oblivious to others. I dont want to report him to the police and get him in terible trouble and nor do I want him to stay on the road and maybe kill someone. Please help I dont know how to tackle this? thank you
