Soldato
My father had major eye issues and was on a restricted/short licence from about 40, he actually gave his licence up at about 60 because in his words "I didn't want to be like Sam*" who was our slightly older neighbour who was driving against doctors advice and IIRC had something like 5 minor accidents in a couple of years (not to mention driving at about 15mph in 30 limits).
People might disagree but I reported my grandfather (in his 90s) as he refused to give up driving but was an absolute danger to himself and others. Paid no attention to other road users, junctions etc. I did it anonymously so that he wouldn't know and the DVSA called him in for assessment via ROSPa. He didn't even get through the basic cognitive tests so they revoked his licence on the spot.
