I would say Tony Stewart. jr just didnt like the way his car handled and they claim its going to be 15 degrees warmer tomorrow than today.
Now, the better question is, who will survive the big one?
FYI, most of those cars really turn left if you let go of the wheel. THey are cambered to take the corners, so to go straight you have to turn right slightly. Funny feeling really. On road corses they set it nutral so the car goes straight.
