Mercedes-Benz's entry for 'Design Los Angeles 2007.' The SilverFlow concept will be built from micro-metallic particles that can be assembled and disassembled by way of magnetic energy. That means instead of garages, we'll be able to park our cars in duffel bags. When drive-time comes, reassembly will be a matter of pushing a button on a smart key fob and getting the hell out of the way. Plus, the idea of cars returning to the look of 1930s Grand Prix racers will totally add a whole Fritz Lang vibe to the future.
