Welcome to WWE racing, where scores are settled by drivers moving at 200 mph, where anarchy reigns, where NASCAR's new boys-have-at-it ethos has produced a kind of automotive Darwinism, highbrow demolition derby.It's all great fun, wonderful theater, just the kind of on- and off-track conflict that can drive NASCAR's flagging ratings and interest.
That is, until somebody gets hurt.
Or, well, dies.
This is the question in the wake of the Carl Edwards-Brad Keselowski mash-up at last week's Nationwide Series race: How far is too far? When and where is NASCAR prepared to draw the line between rubbin'-is-racin' and the kind of Wild West ugliness that tears up cars and could, heaven forbid, leave NASCAR with another Dale Earnhardt tragedy?
