Will we ever get a truly car-free city?

Oslo is the latest city to announce plans which shift the focus away from cars - by banning all private vehicles from the centre by 2019. Car-free days have slashed pollution in Paris while new eco-cities are aiming to design out the need for vehicles - but will cars in cities ever be consigned to history?

When Oslo revealed plans to ban all private vehicles from the centre by 2019, it joined a lengthening list of cities seeking to shift the focus away from cars and towards greener, citizen-focused mobility solutions.

Around 7 million people globally are estimated to die from air pollution every year, not to mention the millions more killed in accidents involving motor vehicles.
