Do you get in and out of a car from a wheelchair?
This is the point I made in my post upthread. Even if a person uses a wheelchair or mobility scooter, if they can’t get in and out of a car, life becomes rather difficult. Admittedly the cars the Queen uses for state events, such as the Commonwealth service today, will be bigger than our VW Passat, but my mother really struggled to get in or out of ours. Strangely she found getting in/out of my little Hyundai i20 a bit easier if she used the front passenger seat, but not a lot easier. Mother was not gracious about it either, she nearly snapped my head off when I commented on her difficulties, claiming she could do it perfectly well.
Pure speculation, but maybe the Queen doesn’t want to be seen to struggle getting into/out of cars.
