Maybe people don't know they are bicycle racks?
Interestingly, at the Navy Yard Metrorail Station, there are two sets of bicycle racks, one by the street is a typical utilitarian set, while the other, installed by the developer of the adjacent property, employs "arty" architecturally forward racks.
When I was in the area on Wednesday, I noticed that the architecturally forward racks were unused even though they are closer to the entrance, and better placed in terms of the potential to get smacked by an errant motor vehicle.
