Like every year, International Mobility Week has recently been held in many urban centres in Europe. A healthy word has been added to this year’s motto for a sustainable mobility model: “A day without a car for your health.” Given the sponsorship messages of the house that has been imposed in the last year, we are at the time of remembering that the street also cares for us, which is an area to recover. And for the street to be a space of coexistence it has to be necessarily safe and clean. No car, among others. Therefore, the idea of creating “Low Emission Areas” in cities has an increasing impact, as we do in rural areas, nature protection areas. In these urban shelters it is ensured that the nitrogen dioxide emitted by cars and the presence of fine particles is acceptable. They are literally urban respiratory areas, limiting the presence of highly polluting vehicles. It's another urban tool for polluting broadcasters to gradually disappear from cities. Imagine that cars circulating on the urban fabric of Cerdá in Barcelona of the future are not transporting people because the streets will be forced to move objects and products.

Freedom of movement is the triumph of advanced society; the ability to transport people and products – and viruses – over long distances and in a short time. Mobility is therefore the territorial, economic and food axis. And mobility, in addition to pollution, needs great economic investment and great space, both in the territory and in the public space. If the mobility model of the future sees the territory deflated by car, the public space of the territories and cities that will liberate the car should be won by the citizens, we will have to be vigilant.
