DARPA's Urban Challenge race starts this morning at the former George Air Force Base in Victorville, California. The race is described as:
The teams will attempt to complete a complex 60-mile urban course with live traffic in less than six hours. The finalists will operate on the course roads with approximately 50 human-driven traffic vehicles. Speed is not the only factor in determining the winners, as vehicles must also meet the same standards required to pass the California DMV road test.
The race's web site is very slow but updates should be available on other sites such as Wired or TG Daily.
