And you produced this "fact" based on what?
Oh I don't know, how about the "Fact" that the icon on the handicapped space IS A PERSON IN A WHEELCHAIR!
Or how about the "fact" that handicapped spaces first appeared next to a "cut out" in the curb!
Or the "fact" that the original handicapped spaces were half again as wide as non-handicapped spaces! So that people would have the extra room to get in and out of their wheelchairs!
Or how about that old public service commercial where the disabled vet is struggling, trying to maneuver in and out of his wheelchair while having to park in a normal space, because some lazy bimbo who didn't want to walk a few extra feet parked in the handicapped space.
Do I really need to go on?
Don't know about the poster, but I have stated the same thing, based on several reasons.
Having personally lived through the process of creating the damned things and the debate that surrounded the ADA, and the subsequent piling on of every conceivable "i;;ness", including, presumable alcoholism, and...
Over 40 years of designing, processing and supervising the construction of thousands of them and...
Having seen the legal abuse and scamming of the system by others.
Most of the users of handicapped spaces aren't.
