Controversial sedan service/possible John Galt front group Uber has come out with new data about its fares in Washington, and one thing is obvious: Capitol Hill residents really like staying in Capitol Hill.

Uber tried to find out which neighborhoods in the cities it covers have the most trips between them, but the data revealed that a large amount of its trips are just around Capitol Hill. “These neighborhoods have some kind of activity gravity keeping people within them, and that’s fascinating to me,” writes Uber blogger Bradley Voytek.

Uber’s other tentpole neighborhoods cluster around downtown, with Logan Circle, Foggy Bottom, Georgetown, and Columbia Heights as major hubs.

One of Uber’s selling points has been that its drivers will take fares for neighborhoods east of the river that traditional cabbies refuse. Interestingly, though, the map shows that those trips account for just a small percentage of Uber’s fares.
