Rookie race car driver JR Hildebrand made a rookie mistake, and lost the Indianapolis 500 to Dan Wheldon in the final lap.
Hildebrand came up on another rookie, Charlie Kimball, in the fourth turn. Hildebrand didn't back off and slid to the outside, and lost control. He slammed the wall, allowing Wheldon to drive into Victory Lane and win the famed race.
Take a look at the video, and see for yourself how it all went down on Sunday.
