When I was back in undegrad in Aeronautical Engineering, one of the professors at my campus had a great little car.  I finally found it (I think) at the Tiny-Cars post on haha.nu!

This was the coolest thing ever, as it was as long as a regular car was wide, so parking was super easy – parallel parking was non-existant.  You just drove it up to the curb.  It was protected from the elements, and you had a nice, easy entry and exit.  For today’s green tech push – why not release an update version of this?
