NASCAR Crash: Carl Edwards and Brad Keselowski Show Bad Blood at High Speed

March 8, 2010— -- NASCAR's governing body announced new rules for the 2010 season that encouraged drivers to show more emotion to re-energize a sport seen by some as growing stale.

Drivers Carl Edwards and Brad Keselowski took those rules to heart, as anyone watching them race at the Atlanta Motor Speedway Sunday can attest.

The two cars had jockeyed for position for several minutes when Edwards, in car No. 99, gently nudged Keselowski 's rear-left tire in car No. 12. That "gentle nudge" -- at over 190 mph -- sent Keselowski into a rapid tailspin, spinning into the air. The car landed upright after shocking the crowd and television audience.

"It's not cool to wreck someone at 195 miles per hour," said Keselowski after the incident.

Keselowski walked away unhurt from the crash. Edwards was disqualified.

"The scary part is he went airborne, which is not at all what I expected," said Edwards. He continued on his Facebook page, writing "My options: Considering that Brad wrecks me with no regard for anyones [sic.] safety or hard work, should I: A-Keep letting him wreck me? B-Confront him after the race? C-Wait til [sic.] bristol and collect other cars? or D-Take care of it now? I want to be clear that I was surprised at his flight and very relieved when he walked away. Every person has to decide what code they want to live by and hopefully this explains mine."

The two drivers have gone after each other numerous times in the past.

At Talladega, Ala., in April 2009, they were both part of a tightly-bunched pack of cars when the two collided. The brush sent Edwards careening into several other cars and into the stands. Seven people in the crowd were injured, and the number might have been higher if not for safety netting around the track.

At a race in Atlanta, the two collided again. This time Keselowski came up underneath Edwards, sending him crashing into Joey Logano along the outside wall.
