If I see a car with a placard then there is nothing i can say or do. Like some said here, it may not be that obvious a handicap.
BUT.....
When i see a car in that spot with no placard or HP plate, and if I see them, they get an earful from me that would make some people blush. I just can't stand that crap..I have to take my mother around some weekends and I use/we her placard where we go. If some D-bag is taking a spot without a placard; man do I see red !!!
