Parking on the Surface of the Moon

At what point does the surface of a parking lot become so rough that a parking space is only "accessible" in a theoretical sense? Took this photo yesterday in a parking lot in my neighborhood--it's one of two side-by-side designated spaces in such rugged pavement. Making it more worrisome, these spaces are in a lot that serves both an elementary school and a senior center. (Oh, and it's about two blocks from a recent big-budget accessible home-building event shown on national television.) I assume this is out of compliance with the applicable codes, but it's also just obviously dangerous. And I also assume it's not the worst example of its kind.
