I imagine the designer was under a set of constraints, for example, only a certain about of linear space was available for the ramp, because of other issues in the area; or maybe there was some budget constraint.
The designer may have thought about what it's like for a cyclist to make that curve, and thought, "the bicyclist can slow down to make the ramp."
None of those things have anything to do with not caring.
