Let me start by the beginning. The grounds appeared in China as a consequence of a characteristic cyclist behavior. It consists in a cyclist waiting in an intersection until a group of bikers is created. Once they have the sufficient power and visibility, they can cross it and force the cars to stop. By the way, the name of “critical mass” is taken from this film.
Then, it jumped up into the U.S. and specifically to San Francisco as the first “official” Critical Mass. Here, the participants had to fight against the lack of understanding of local authorities and dramatic actions were even taken. The documentary We are traffic! shows those initial moments. As you can see, the atmosphere was committed with all the participants wanting to spend a good time while at the same time they defended claims such as a better world, pollution reduction, practicing more sport, reducing street accidents and so on.
Today it is celebrated in more than 300 cities worldwide once a month. The specific date varies between places and it is a good idea to contact with local bikers to join it. So remember, if you see suddenly cyclists on the street, let’s say dozens, hundreds or even thousands, you would be probably seeing the Critical Mass. It could also be possible that it did not still exist where you live. If this is the case, why don’t you start it?.
