where do we disagree?

And in automobile racing, if anything I would imagine a lower weight would be advantageous, though the difference would be miniscule.

The engineers and mechanics have figured that out too. Which is why every major series has minimum or target weight requirements for the set of car + driver + fuel (if refuelling is allowed), ( and + oil next season Formula 1).

This was broached deep because of: Danica Patrick.

The ideal weight is about 165lbs. If you're lighter, you're too vulnerable in crashes. If you're heavier, the set's weight distribution suffers. A lighter driver breaks on contact; a heavier driver is dead weight in a bad position inside the car.

We're back to square one.
