Don't you think they are getting more and more common nowadays?
I seem to see more wheelchairs and especially mobility scooters than I have ever done so.
Admittedly, many are used by older people who are using them, not perhaps because they are disabled, but because it makes life easier for them – and why not!!
Surely all these wheelchairs make the general public more aware and understanding of disabled people. As more and more of us wheel around the pavements people will just tend to ignore us (in a nice way) and let us get on with our daily lives.
Have you seen more wheelchairs where you live?
