The document discusses the $2M DARPA Grand Challenge, an autonomous vehicle race across the desert. The motivation was to develop autonomous supply lines for the military, but it ended up spurring civilian applications instead. The author was on the Stanford team that won the race. Though it failed to create autonomous military supply lines, it helped advance technologies like LIDAR and inspired applications at Google for self-driving cars and Street View. The success of the challenge was due to pre-existing relevant technologies, a large prize amount, support from DARPA, and companies able to commercialize the results.
