He has led a privileged life (I am not attacking him for that, BTW).
If it is true that he has "never learned to drive", that doesn't mean that he hasn't tried. Some people simply never learn all of the necessary skills and either give up or undertake legendarily large numbers of driving test fails before passing.
What it's probably safe to say is that his failure to learn to drive as a young man - during WW2 and the immediate post-war period - was nothing to do with the environment, global warming (whatever that is now called), etc. Either he couldn't master it or he didn't need to because others were prepared to drive him around.
