New York Times: Google has been working on cars that can drive themselves, using artificial-intelligence software and a variety of sensors. So far, seven test cars have driven 1000 miles without intervention from either the human behind the wheel nor the technician in the passenger seat. Developer Sebastian Thrun, director of the Stanford Artificial Intelligence Laboratory, believes that robotic cars would lower the nation’s energy costs and make highways saferâmdash;because robot drivers react faster than humans and don’t get distracted, sleepy, or intoxicated.
