City planners in Beijing don't seem to get the concept of the "bottleneck." Personally, I learned about this concept in business school for project management, finding what in a process is slowing things down, or causing delay, essentially limiting production. They don't seem to get that here, lots of lots of bottlenecks are what make Beijing traffic known for being bad.
Here is a video that was taken over golden week, which is a major holiday in China, in October, second largest holiday behind Chinese New Year. This is what happens when everyone tries to drive back into town and gets hit at the toll booth.
What made me laugh the most about this video isn't the video itself but the fact that from up high it actually looks much more organized than it is in real life. Traffic rules do not apply, each man or himself.
