Certainly don’t know the specifics of location or where most people work in DC, but if people are commuting from the suburbs and need a safe place to store their bike/change in the city-I could see the use.

You might have to walk or take the metro to the office, but it beats rush-hour auto traffic.

One of the reasons I ride my bike is that I can park it directly in front of my office.

I’d rather leave it locked on the street close by than have to travel to some central location to store my bike then walk/subway/bus back to the office.
