Roads? Where Matthew Riese is going, he doesn't need roads. He built this amazing hovercraft after raising $5,644 on Kickstarter. Riese's motive was a worthy one:
It's the year 2010, a new decade is upon us, and the question everyone is asking is, "Where is my flying car, already?!" What I'm building isn't a car, and it doesn't "fly", exactly, but I think it's a step in the right direction.
