The only way to get real action?

In the city of Delft in the Netherlands, a group of neighbors were fed up with cars speeding down their street so one evening, under the cover of darkness, they dragged old couches and tables into the middle of the street. They arranged the furniture in a way that did not block the traffic but did force it to slow down as drivers had to negotiate their way around these objects. Shortly, the police arrived and, while noting that this action was clearly illegal, also admitted it was a really good idea. Soon, the municipal government was creating their own more permanent version of the neighbors’ old furniture—and the idea of traffic calming was born. It is now used all over the world to make streets safer for everyone by helping drivers slow down and recognize that the street is not just for cars.
