Saturday in the DARPA Urban Challenge. The final event pits 11 vehicles in competition for a $2 million first, $1M second, and $500k third place prizes. The 60-mile course at the former George Air Force Base in Victorville CA must be successfully navigated in less than 6-hours while avoiding about 50 carbon-based drivers. Can Stanford repeat their 2005 Grand Challenge victory with "Junior" or will Carnegie Mellon's "Boss" (pictured) bust out a BFG-9000 in swift retribution? Tune in Saturday to find out.
