Rolfe what about all the disabled badge holders who have obviously got the car because they care for a relative or similar. They really p*ss me off when they take the disabled spaces purely because they have the badge. Yeah they could be going an errand for the person who the badge belongs to but does that give them the right to use the space when some other poor punter who can't manage, can't get a space at the door. Does that not annoy you if you are out with your mother and the spaces are taken?
Ah don't get me started 
That sort of behaviour is very risky indeed. If you park in a disabled space with no badge, not a lot is likely to happen to you as things stand. If you park there with a fraudulent badge - and that includes a badge belonging to a relative who isn't in the car - the sky is likely to fall on you. This is because it is seen as fraudulent use of the badge, rather than just parking where you shouldn't have.
As far as I know, there is no entitlement to use the badge if you are simply running an errand on behalf of the disabled person. Otherwise I could use the thing every time I go to Tesco - which I don't, obviously. I have parked in a disabled space once or twice with her in the car, and then she's said she'd rather sit in the car and not get out. I don't know how legit that is, maybe I should have moved the car at that point. However, the thought of having to do it all again when she later decided she actually wanted to use the Ladies Room (almost an inevitability) kind of put me off.
But the bottom line is, if you have someone else's blue badge in your car, and you decide to be a bad person and park in a blue badge space even though you yourself are perfectly fit, the best thing you can do is hide that blue badge. It's the difference between a rap on the knuckles and a conviction for fraud.
And I'm not advocating parking in a parent-and-child space if you don't have a sprog. I'm merely complaining that these spaces crowd everyone else away from the close-by parking area. I've seen young mothers with perfectly mobile six-year-olds use them, while older people (not blue badge material obviously) are struggling in from the far reaches of the outfield in pouring rain.
