Like we ever let that stop us. We had a parking ramp here where I live that allowed parking on the ramped areas but not on the level areas. My analysis was that the ramped areas were the levels (1, 2, 3, etc) and the level areas were the transitions between the levels. This meant that the whole could be defined as a step function and a step function can have the points of transition defined or undefined and, in our case, they were undefined, so there was no there there on which to park.
