Australian designer Charles Rattray has let imagination run wild with his Autonomo 2030 concept car pictured below. He envisions a fully autonomous electric car with a multi-layer nano-scale surface which includes solar cells. Windows can be switched between opaque and fully-transparent modes. Multiple such cars can automatically travel together in distances of 20 cm thus significantly reducing drag and energy consumption. The autonomo is not much longer but significantly narrower than the Mini and can carry up to two adults seated behind each other. Linked in a flock, two Autonomo vehicles should be able to use a single lane on many streets. Combined with inter-vehicle communication and synchronization this should do much to eliminate traffic jams.For more info see the detailed concept.
