Auto racing (also known as car racing, motor racing[1] or automobile racing) is a sport involving the racing of automobiles for competition. The main aim of an individual event is to set the fastest time in a set number of laps or time limit. The finishing order is determined by race time, with the fastest time in first place, second-fastest in second place and so on. Any driver failing to complete a race for any reason is deemed "retired", or, more commonly, "out". Retired drivers will have their positions determined by the order in which those retired, with the first to retire finishing last, the next second-last and so on.
