Just watch the first 60 seconds...I especially like the dillweeds who get out of their cars to walk around as other cars are still piling in. Didn't they teach us to never get out of our cars on the racetrack in DE events? ;-)
Who knows, maybe these were all just Southerners passing through. Or it was ice...yeah, that's mostly what we get on the roads of Atlanta too. :)
Too bad people were injured...I feel for them.
Still, it's good to see that these folks aren't as good of drivers as they often claim to be. As I've discovered in my HPDE days and now with racing, you're not nearly as good a driver as you think you are. It's humbling, especially in Spec Miata!
