THought 1: No way USSS would let him do that.  I'm guessing he hasn't driven a car since college. Thought 2: That's a hell of a driver.  I've driven armored vehicles on tracks and it isn't as easy as one might think.  An uparmored Tahoe is 10,000 lbs.  Try running one of those bacckwards through a slalom at 50 mph without rolling it...
