When a company rolls out a concept car that has an associated iPhone app that controls it, you know that you're looking at a product that's gone from viral to mainstream:

At the touch of an iPhone app, the streamlined rear end of the one-seater pops up to make room for two more people. The adjustable rear end conserves energy by maximizing aerodynamics. The idea, company founder Frank Rinderknecht says, is to create lightweight, streamlined and efficient zero-emissions "individual mobility" that can adapt to suit the driver's needs. The iPhone controls everything from the canopy - there are no doors - to the ignition.
