Performers of vehicular stunts require extensive training and may employ specially adapted vehicles. Stunts can be as simple as a handbrake turn, also known as the bootleg turn, or as advanced as car chases, jumps and crashes involving dozens of vehicles. Rémy Julienne is a well known pioneering automotive stunt performer and coordinator. A Guinness Book of World Records holder stunt driver, Bobby Ore, performed in numerous movies and events and holds a world record for longest distance driven on two wheels in a London double decker bus (810 feet).
