In 2007, the DARPA Challenge course was changed to an urban setting, requiring competitors to integrate with traffic. Six teams completed this challenge, headed by Carnegie Mellon’s Tartan Racing with Stanford and Virginia Tech’s entrants following close behind. Other competitors, however, were involved in accidents – the MIT and Braunschweig entrants collided, and another competitor set itself on a course to collide with a pillar. This event gave rise to the predictive and decision-making software required for autonomous vehicles to operate amongst other traffic – as well as public awareness of the mistakes this software can make.
