The World Figure-8 race is held annually at the Indianapolis Speedrome, and involves cars racing each other on a figure-8 track. This isn't your typical car race, where the drivers just focus on speed. Instead, as the race progresses, and each car speeds up, drivers have to worry about avoiding any collisions at the center of the 8 figure.
Needless to say, there are a few incredibly close misses, but surprisingly, no collisions.
