Its fascinating to see problems in other states. Locally (thousands of miles from CA) the "new urbanists" have a stealth strategy for discouraging car use which is to write ridiculous handicapped requirements into zoning laws. So new stores have to have 20 to 30 handicapped spots to discourage car use by the 99% unhandicapped customers. So no matter how big your parking lot is, and how packed it is with customers, roughly 20% of spots will always be empty. Its an interesting strategy for banning cars, they're not technically banning cars from parking, its just parking now requires a handicap tag. It has the pleasant side effect that even at major sporting events I've never actually seen a parking lot with all handicapped spots filled, which must be very convenient for handicapped people.
There are other problems. I used to work with a guy in a wheelchair and life for those people is hell, at least once a week when his non-handicapped brother picked him up in the lift van after work, some do-gooder would scream at his brother for being evil enough to park in a handicapped spot, he would even get blocked in until the cops arrive, do-gooders just make life for everyone awful.
