I am sure I saw a news item recently where they were discussing the fact that new laws were required to have the disabled parking spaces enforced. If that was right then I am confident the "Parent & Toddler" spaces (sometimes men park in them and every now and then they even have kids with them

) are not enforcible.
Friends of mine had a severely disabled daughter and so they had the badge - on one occasion they were parked in a disabled space and some very considerate person blocked them in!?! WTF. Anyway, they ended up getting the police to come and help move the car (I think the owner was found before the police could get a truck in to move it, as it happens). Whilst chatting to the police their advice was simple - if you're disabled and someone without a badge is parked in a disabled spot, just block them in. Provided you are genuine, you will not get into any sort of trouble ...
Tut - you could take on some sort of vigilante (sp?) role where you cruise the country at top speed, as per usual, scanning car parks looking for perps to block in, then go for a wander around the shops or a spot of lunch, before returning to bemused victims

Double points if you can overtake the very same car on a blind corner 10 minutes down the road
