There have ALWAYS been hot tempers and fights after stock car races...as long as I can remember (even at the local speedways around Atlanta).
Anyone else remember Bobby and Donnie Allison and Cale Yarborough brawling on the backstretch after a crash at Daytona in 1979? What about Bill Elliott and Dale Earnhardt after the Winston in the mid-1980's?? (after Earnhardt wrecked Awesome Bill...why I was never a fan of #3).
I also remember Kyle Petty going after Bobby Hillin Jr at the 93' Daytona 500....Kyle is a very laid back guy; yet he was wrecked while leading the race and lost his temper.
Hot tempers and fisticuffs are as much of Nascar history as checkered flags and victory lane. Heck, I'm laid back and wanted to take Kevin Harvick's head off after he spun #24 at Watkin's Glen last week....if I'd been Gordon, I'd have knocked Harvick's teeth out for that stunt.
IMO getting the cops involved in a fight between two racers is ridiculous. If Kurt Busch is too much of a wimp to fight his own battles without swearing out a warrant for the other driver's arrest, he needs to find another line of work (what next...lawsuits over who caused the "big one" at Talladega?
BTW - I'm not a fan of either Kurt Busch or Jimmy Spencer...Spencer's a hothead and Busch is a pompous little smart#ss.
Just my .02 cents worth...from a lifelong Nascar fan.
