The hardest thing for my Dad when he did that was handing me the keys so that I could drive him when he needed to go to hospital appointments......and yes I did tease him, he would have thought i'd gone daft if I didn't. Boy was he a backseat driver and of course I told him to 'zip it Dad it's MY licence that driving' naturally he swore at me. I wish he was still here to swear at me again.
Any prosecution/court would take into consideration that the person has taken action to ensure similar won't happen again. It is difficult for anyone to give up their licence - not giving up on things just because you reach a certain age helps you survive longer. Don't really know why we would be watching for anything to happen or not happen.Call me cynical but.........I suspect it was a case of surrendering his licence, thus rendering any potential prosecution ‘not in the public interest’ ............watch this space.
