The multi car pile-up at CART's 1996 U.S. 500. What made matters even funnier, was ESPN announcer Bob Varsha praising the professionality of the CART grid...only for the pile-up to begin. In hindsight, this might qualify as an Epic Fail for CART.
It gets even better, when you consider that many people predicted the IRL's Indy 500 to be the crashfest of the weekend. To sum it up: The inexperienced rookies from the Indy Racing League started way better than the experienced pros from CART.
The 2011 New Hampshire race. Will Power flipping BOTH birds to the race officials for their decision to restart the race under wet conditions. Enough said.
