I dont think people forge blue badges to get a big space at Sainsbury's. They do it to get free road parking.
You may well have someone using a blue badge who no longer needs it but they do have to be renewed so if their GP thinks they no longer need it when it expires they wont get another one.
FFS re new cars! Of course disabled people on mobility have new cars because up until recently that was the only sort you were allowed! They are leased and they are not free. To get our new one we had to find a deposit of £2000 btw. We tried to get a used car so we could save on the deposit but we were not allowed.
I am another one that remembers the dark old days with no P&C parking. We all starved for lack of door opening space and close proximity to the doors. When it rained we kept the children safely indoors less they melted away.
What is most annoying about this thread is that peoples' negative opinions seem to based entirely on misconceptions i.e. you have to look disabled to be disabled, disabled people get given brand new cars, you cant be disabled if you have a sports car (you can if you have a £10000 deposit to put down), blue badges are handed out like sweeties, everyone knows somone who has a a badge but doesnt need it (report them then, make life easier for the rest of us), blah blah.
When people who know the score refute these myths they are ignored. Far easier to imagine that being disabled is one big ol perk after another.
