I understand what you are saying, but sometimes you can't tell a person's disability by looking at them. I had a dear friend who had a placard because she had respiratory problems to the point she could not walk far; she would just lose her breath. She got a lot of dirty looks for using handicapped spaces, but then her illness progressed to the point where she could no longer walk even short distances and had to get a scooter.
My husband has never gotten a placard, but is eligible- he can walk also; but only short distances. His legs were injured by a mine in Vietnam, as he ages his joints hurt badly if he has to walk far at all. My sister had one when she was terminal with cancer- you just really can't always tell by looking who really needs the handicapped spaces.
Of course, I agree. However, when there are 50 handicapped parking stalls at the local mall or where ever, it's clear after watching people come and go, walking as normal as any perfectly healthy person, very few are legitimately physically handicapped to the point where they need or require front row parking.
On the flip side of that, many times I've seen supermarkets where the parking lot is jammed where there are few if any available places to park, yet there are 20 unoccupied handicapped spots. I could see 2 or 4 parking bays for those that honestly need it, but now there are dozens. It's ridicules.
I have often wondered how many times someone that is wheelchair bound can not find an empty handicapped parking spot because they are all taken by people that got their physician to sign off for a placard for less than legitimate reasons.
Like Hollywood actress Kirsten Dunst (from Spiderman) here?
