Because the John Force and Tony Pedregon "fight" at Indy was manly.
The Ambrose/Mears deal was back in May, but yeah Mears got what he deserved. Generally NASCAR drivers have more people looking after them in terms of potential suspensions and penalties. Funny thing is the "fight" isn't really that big of a deal anymore, tonight in Charlotte more people are P/O'd about the Panthers Bengals finishing in a tie.
I remember an incident between Jeff Gordon and Mike Bliss after the Chicagland race in 2005 where Bliss wrecked Gordon and supposedly the two of them were at the same airport getting on separate planes for Charlotte. The only thing that is known is that at the following weekends race Mike Bliss was sporting the remnants of a pretty nice shiner.
