Yeah I saw it this morning. Tony Stewart, the driver who struck Kevin Ward, is one of the most well-known racers in America.
From what I have read, Stewart was questioned and released, and the case is not being treated as a criminal matter. However, I can't help but agree with Thork about the video. The caution flag was up, and in the video, the car before Stewart's slowed down and passed Ward way inside. Stewart, however, came in pretty hot and seemed to swerve in the direction of Ward. It seemed pretty malicious, but it's pretty hard to tell from the angle I saw.
Thork/mods, you should make this thread a poll. I am curious to see if TFES thinks this was an accident or not. Other sources I have read about seem pretty split about the intent of Stewart.
