London, Berlin, Paris, Toronto, and an increasing number of cities are aiming to reduce traffic congestion, polluted air, and valuable urban space occupied by parked cars through policy changes that promote walkability, pedestrian- and cyclist-friendly (and in certain cases, car-light or even car-free) city centers, and an overall improved quality of life.

Oslo became a closely monitored model of a hybrid approach: after the proposal of a complete ban of cars in the capital's center was met with fierce opposition from business owners, who feared decreased commerce, the city decided to close off only certain streets to motor traffic but replace the more than 700 downtown parking spots with bike lanes, greenery, and pedestrian-oriented infrastructure.

"Cities, like Oslo, have been built for cars for several decades, and it’s about time we change it," Hanne Marcussen, Oslo’s vice mayor of urban development, told Fast Company. “I think it is important that we all think about what kind of cities we want to live in."
