Gosh cant believe I havent seen this thread before!!
As a disabled driver myself (wheelchair user) it also narks me off seeing these things get abused.
I have stickers in my rear window asking people to leave me space to get my wheelchair in and out yet people choose to ignore them. One of these days I'm going to just let the tailgate open into someones car rather than sit there waiting for the culprit to return.
A lot of able bodied people seem to think we dont matter or just dont think at all about the way they treat disabled people, a little consideration would go a long way.
At my local Asda I regularly see taxi drivers (the worst offenders) and Police parking in disabled bays or blocking access to disabled bays jsut so they can get to a cashpoint. One of these days I'm gonna go militant on them and block them in with my car and leave it there, especially the taxi drivers - hitting their earnings might make them think a bit more next time.
Even those who say they only do it late at night - why is that justification? Most wheelchair users I know prefer to do their shopping late at night as its quieter. How can anyone know when a disabled person is likely to turn up and need to park?
We don't particularly want larger parking spaces or for them to be closer to the shop, its a question of need, not want. When I'm getting in and out of my car I need access to the drivers door and the tailgate. If either of those is blocked I can't go anywhere, simple as. I didn't ask for this need and certainly don't want it, butI have it so have to jsut get on with it.
I don't necessarily agree with the blue badge system either, mainly because I know several disabled people who are genuinely disabled but canot get badges as they refuse to claim DLA. Its scandalous that some councils refuse to issue badges to disabled people simply because they are not claiming a benefit that they dont want, but thats another story.
Finally please be careful who you harass in car parks - there are many people who are genuinely disabled but have "invisible" disabilities, particularly those with MS and various mental health problems. They are just as in need of assistance as someone who uses a wheelchair. It could even be argued that us wheelchair users don't necessarily need to be closer to the shop as we don't have to walk. I've heard that one before.
I agree with most of your post, and as said, I won't use these spaces unless there is no other supermarket/work parking (on places round here likely to get so busy that no other choice).
However, the 'invisible' disabilities, which I agree with, do not account for some of the orange badge abuse I see - perfectly abled people, not requiring help, using these orange badges to get free parking near the shops. I suspect a lot of people borrow badges/cars from disabled family members etc.
