Now what they need to do is something that's years overdue - change the disability symbol. One problem with any disability facility, be it a loo or a parking badge, is that people can easily assume that someone without a wheelchair is cheating.
That's understandable since theft of blue badges is a problem and also some people do cheat, but even so, it's time for another symbol. What symbol, I don't know. Maybe the current symbol with a plus next to it.
