A curious thing appeared on a downtown DC sidewalk this week: Dedicated lanes for pedestrians talking on cellphones, with an express lane to the side for everyone else.

The lanes aren’t a half-baked experiment from DDOT. They’re actually a stunt from National Geographic.

National Geographic workers added the sidewalk lanes on 18th Street NW between K and L streets, with permission from DDOT, to film people’s reactions for an upcoming TV show about human behavior.

Film crews recorded pedestrians’ reactions for several hours yesterday. The most common reaction seemed to be curiosity, but according to Yahoo! Tech columnist Rob Pegoraro, the new lanes did inspire many people to move to one side or the other.

This might have drawn inspiration from a “tourist lane” New York-based group Improv Everywhere painted on a Manhattan sidewalk in 2010.
