Rickshaw Traffic Jam
I keep calling these rickshaws. I guess whether you're walking or pedaling, it's still the same name. Maybe more accurate is a "rickshaw tricycle". Anyway, get enough of these in a narrow street and you've got a traffic jam.

These guys may have been busy but elsewhere in Beijing, like outside the forbidden city, they're aggresively looking for customers. Perhaps they suffer from a reputation of overcharging or perhaps it's just cheaper to take a taxi, but either way, declining 20 rickshaws seems to just make the 21st rickshaw even more certain that he's just the guy I'm looking for.
