Imagine racing your favorite Nextel Cup style stock car on a banked oval speedway at scale speeds of over 100 mph!  You're in complete control as you head into the high speed banked curve, your left hand gripping the full size steering wheel, your right hand on the shifter, your heart pounding as you go into turn 3 with the throttle wide open - when all of the sudden it happens - the car behind you taps you as he tries to nose to the inside - sending your car spinning up the track, out of control and into the wall as another car "T-bones" you when you slide in front of him.  No worries! You may be a lap down, but you're not out.  Just shift into reverse and you're back in action!
