Drivers are turning cities across the country into their own personal racetracks. Videos posted to YouTube show hot rods wreaking havoc. In one recent video from New York's Times Square, an officer was nearly run over when he tried to stop a car. In San Francisco, a clip showed three cars bringing traffic to a halt as they did doughnuts in the middle of the Bay Bridge. While police officers try to keep order, it's often a losing battle. But it may come as a surprise that much of this mayhem is actually organized. #InsideEdition
