When Clint Bowyer spun out with a flat tire Saturday at Richmond International Raceway, there was speculation among fans that he might have spun out on purpose to bring out a caution flag.

That caution flag enabled Bowyer to pit and he ended up on a pit cycle that allowed him to stretch his fuel-mileage en route to the win.

Spinning out on purpose to bring out a caution flag is illegal, and NASCAR likely would have penalized Bowyer at least a lap if it believed he intentionally caused a caution. Similar accusations were levied toward Bowyer teammate Paul Menard last year at Richmond.
