The MDI Airpod is a minuscule concept which mates a compressed air engine similar to the one that'll go in the Tata Nano with wacky futuristic styling and a tiny footprint perfect for city dwellers intent on automotive-assisted suicide. At just 81.5 inches long and 63 inches wide, the Airpod manages to hold three people and a child along with its compressed air tank, the zero-emissions engine, a joystick for steering, and not much else. Our first response upon seeing this latest transportation concept? "Sweet hellish death trap!" Regardless, production may begin as early as the spring of 2009, with crumpled green piles of air car popping up on roadways shortly thereafter.
