Every day hundred of thousands ride the bike. Some of them use bike lines and / or roads together with cars and motorcycles. This last fact makes possible to discover the real violence on the streets. Yes, you have read violence. And I am not talking about the undesirable, possibly common bike accidents. I am referring to a subtle, invisible force with capital letters. It is easiest to discover if you live in a city in which urbanism have been developed under bad, people-damaging, car-oriented premises, meaning with wide and straight avenues, long distances between zebra crossings, and few speed radars if any. Perhaps you have get used to it without realizing how harmful and noxious it is. Paying a little bit of attention of the car drivers stuck in traffic jam behavior helps to discover it. Moreover, if you were able to determine each and every speed car in those avenues, you will astonish as most of them do not fulfill the traffic regulations. Furthermore, cars do not often respect the security distance when they overtake a bicycle. The use of turn signals to indicate others what they want to make is not frequently use.
So, are public institutions calming the traffic? Yes and no. Yes because every day actions are taken in this direction around the world. But also no since urban traffic is still too violent to be considered as calmed.
