gentleman" but he could barely see if there was any bright light
about. As he got older mobilty became more of a problem and for
anything over 50 yds he did use a wheelchair.

presumably he didn't drive a car?

Not for a good few years before he got the Blue Badge. The Blue Badge
is for the person not a particular car so I don't understand the
relevancy of your question. If I took him shopping we'd have the Blue
Badge in my car, if my sister took him it would be in her car.
