In the more than 50 years since cars seriously invaded cities, both car traffic and the accident rate have increased apace. Fear of traffic accidents has risen even more sharply, with a dramatic impact on pedestrians and bicyclists and their enjoyment as they move about the city. As more cars have filled the streets, politicians and traffic planners have become increasingly focused on making room for even more car traffic and parking. Conditions for pedestrians and cyclists have deteriorated as a result. Narrow sidewalks have gradually become filled with traffic signs, parking meters, bollards, street lamps and other obstacles placed there so as “not to be in the way.” Understood as “in the way of the more important motorized traffic.” Added to physical obstacles are the frequent interruptions in walking rhythm caused by long waits at stoplights, difficulty crossing streets, bleak underground tunnels and elevated pedestrian bridges. All of these examples of city organization have one purpose: to provide more room and better conditions for cars. As a consequence, walking has become more difficult and far less attractive. Conditions for bicycles are even worse in many places: bike paths have been eliminated altogether or dangerous so-called “bike routes” painted on the road next to fast-moving cars, or there is a total absence of infrastructure for bicyclists, who must manage as best they can.
