> High school friction is wrong.

No, it's at least mostly correct. High school friction says

    F = mu * W

Where F is the output force, mu is the coefficient of friction, and W is the normal force (typically equal to the weight).

If it's failed you, it's failed in failing to mention that the tire-road interface can have a coefficient of friction greater than one, and in failing to mention that the normal force can be increased with aerodynamic downforce.

High school physics tends to claim that the coefficient can't be greater than one.

Source: note all the people here who thought it couldn't be greater than one.

How is that due to high school physics rather than naive intuition?

Mine never implied that, and I could have easily disproved it with the grippy pads on my giant calculator.
