Well, that's kind of what Im aiming at. If they want to be treated equal, then they can wheel from the back end of the parking lot in the rain too.
If Im getting what the OP is claiming, than isnt this one of the logical ramifications?
Try getting from a wheelchair with an overhead hoist into a car in a standard parking bay...it's utterly impossible.
Some jerk, with a similar mindset to some here parked my sister in, so that when she finished her Lifeline shift at 1AM, had to drag herself and her chair in through the back of her hatchback, breaking her femur in the process.
At least someone was able to help her out of the car when she sat out the front of casualty blowing her horn.
