An Italian kart racing driver lost his cool, and his mind, on Sunday at a championship race. After being disqualified for making contact with another driver, Luca Corberi stood on the side of the track holding a bumper which had fallen off a car. He waited and waited for his rival to come around a turn and then threw the bumper at him. Luckily he missed and no one was hurt. But later on, he approached the driver he targeted in the pit and a fight broke out. Corberi may now be facing a lifetime ban. You’ve got to see this.
