Having his independence didn't mean turning out for the school run on a wet and windy day, driving elderly parents to hospital appointments ditto OH's, wearing grooves in various motorways to help with childcare, struggling to find a parking space in town, sitting in traffic jams in the rush hour, worrying about MOT, etc, paying for expensive repairs etc., etc.
It just amounted to giving his bodyguards the slip when he wanted to nip off and visit friends. 
How many elderly people would happily surrender their licences if it meant a driver would arrive at the door whenever they felt like going out?
