The New York Times reviews some of the concept cars under development that would mobilize the dense cities of the future.
"Automakers are looking at ways to reduce the automotive footprint. General Motors has shown its EN-V, for Electric Networked-Vehicle, a podlike two-seater for the megacities of 2030. It is currently being demonstrated at the Expo 2010 world's fair in Shanghai.
Ford showed its Start concept car at the Beijing auto show this year. The Start is built of composite panels on a metal frame, with a shape that recalls the New Beetle and Mini Cooper."
