These fuel mileage races seem to be another result of the “law of unintended consequences.” With the COT, we have a field of cars that are almost as identical as the old IROC cars were. Add to that the fact that they are so aero-dependant. And in the years leading up to the COT, didn't we hear that one of the advantages of the COT was going to be less aero? Guess that didn't work out... So, highly aerodynamic, and equal cars mean they can't pass, and now there are much more cars that, once in front of the field, can stay in front. Add to this the fact that the tires don't wear out as fast, so they last longer than a fuel run. I think they should make tires that wear out faster. That would make them come in the pit more, and fill the gas tank up while changing tires.
