SB Nation's Brian Floyd posted this GIF of the moment for which the 2012 Irwin Tools Night Race at Bristol will likely be remembered.
While we're under caution, in a moment of un-abashed bias, I will say that Tony Stewart is my favorite driver - has been since before he joined the Sprint Cup Series in 1999 - and part of that is his passion for the sport. He doesn't suffer fools quite easily, and Kenseth running him up the hill and triggering this accident after Stewart - according to his interview after the wreck - had braked to keep from wrecking the No. 17 is the kind of thing that consistently gets under Stewart's skin.
The defending Sprint Cup champion - likely heading for a fine for the helmet toss - declared in his interview with ESPN that he would wreck Kenseth at any opportunity he had for the remainder of the 2012 campaign.
