HERE’S MORE on the Automotive X-Prize announcement. “Vehicles will be judged on specific market production criteria detailed in key areas such as safety, cost, features and business plan. So this X Prize will only open to practicable cars capable of reaching the marketplace—no concept cars or science projects. . . . In order to win, vehicles must complete both races with the lowest overall time averaged over all scoring stages while still meeting the Automotive X Prize requirements for fuel economy and emissions. While the competing teams might have their mind on how to win and their eyes on the money, the overall purpose of this competition is to capture the public’s imagination to solve economic, international and environmental problems.” Sounds very worthwhile.
