DARPA Urban Challenge T-Shirt, 2007

The 2007 Defense Advanced Research Projects Agency (DARPA) Urban Challenge was the third in a series of competitions organized to promote the development of autonomous vehicles. For this "urban" challenge, DARPA used George Air Force Base in Victorville, California, as a simulated city environment. Competitor vehicles had to maneuver through streets, traffic signs, buildings, and other vehicles -- without human intervention.
