This video of crazy traffic in some Indian town reminds me brownian motion named in honor of the botanist Robert Brown. This is the random movement of particles suspended in a liquid or gas or the mathematical model used to describe such random movements. In this video the random movement of drivers makes me think that the only traffic rules there are as following: 

When you are driving in India never, ever, stop for a pedestrian unless he flings himself under the wheels of your car. The first parking space you see will be the last parking space you see. Grab it.

Learn to swerve abruptly. Indian cities are the home of slalom driving. Never get in the way of a car that needs extensive bodywork. Always look both ways when running a red light.

Honk your horn the instant the light changes. Breakdown lanes are not for breaking down, but for speeding, especially during rush hour. Breakdown lanes may also end without warning causing traffic jams as people merge back in.

Never use directional signals when changing lanes. They only warn other drivers to speed up and not let you in. Making eye contact revokes your right of way.

Never pass on the left when you can pass on the right in India. Whenever possible, stop in the middle of a crosswalk to ensure inconveniencing as many pedestrians as possible. And if a pedestrian ahead of you steps in the road, speed up loudly and chase him back up on the curb. Peds have no rights.

Now seriously, I watched this funny video to see some traffic accident to happen. Nothing!
