The car century was a mistake. It’s time to move on.
Cars were never necessary in cities, and in many respects they worked against the fundamental purpose of cities: to bring many people together in a space where social, cultural and economic synergies could develop. Because cars require so much space for movement and parking, they work against this objective — they cause cities to expand in order to provide the land cars need. Removing cars from cities would help to improve the quality of urban life.
Removing vehicles from our streets would make urban life cheaper, safer, quieter and more pleasant. Repurposed parking spaces and, in some cases, travel lanes would provide ample land for walking and cycling, plus any essential street-running public services, such as light rail, trash collection and emergency services. The surplus land can be devoted to public purposes — imagine Manhattan with sidewalks 15 feet wider and room for sidewalk cafes.
