I don't pretend to know much about racing. It's about as boring as baseball and thus I can't stand watching more than 2 minutes of it in one sitting. However, it seems to me that there's so little left in the hands of the drivers anymore. Whoever has the best car and team seems to win. This race is a clear indication of that as she didn't do anything technical to win at all. She passed a car that in conservative mode because he was running out of gas.
Also, I'm sure she weighs all of 100 lbs. That's probably a big advantage. I hear something about introducing a minimum weight for drivers such that additional weights would be added to the car if the driver was too light. Not sure if that's going to happen or if it already has, but it's interesting nonetheless.
