… he literally wrote Columb’s expression for frictional forces. Then pointed out that that expression overstates the amount of traction that weight gives you

What rules of physics do you propose we use? Ones where dead weight makes you faster? In the ideal case weight cancels out. But it doesn't, it forces you to take corners slower.

But hey, if you don't believe the math, watch an F1 race how the lap times drop and tyre life extends as they use up their fuel.
