So long, Tony Stewart

Here's another fact for you. I think someone said this was the second time by for the cars.

The track is 1/2 mile. Accident at 10 seconds, he was struck at 35. That would be two laps at 12.5 seconds or about ~140mph. How likely, not very with a caution out. For that lap to be a single lap at 25 seconds, the AVG speed would be ~72 MPH which is MUCH more likely.
