I imagine that sport sanctioning bodies may have to address the issue, but it isn't a question that will determine the fate of civilization.
It wasn't so long ago that the NASCAR driver Robby Gordon complained about the advantage that female drivers generally have over male drivers - less weight:
Gordon, a former open-wheel driver now in NASCAR, contends that Patrick is at an advantage over the rest of the competitors because she only weighs 100 pounds. Because all the cars weigh the same, Patrick's is lighter on the race track.
"The lighter the car, the faster it goes," Gordon said. "Do the math. Put her in the car at her weight, then put me or Tony Stewart in the car at 200 pounds and our car is at least 100 pounds heavier.
"I won't race against her until the IRL does something to take that advantage away."
And NASCAR eventually addressed it:
According to the NASCAR rulebook, drivers who weigh less than 180 pounds have to add 10 pounds to their car for every 10 pounds down to 140. Therefore, the maximum penalty would be 40 pounds.
Patrick arrived at Daytona International Speedway weighing 110 pounds, according to her representatives. So theoretically, her car could have been 30 pounds lighter than the car driven by 150-pound Jeff Gordon, who qualified second.
