I didn't miss that. The side which skids first will be the Asbestos
pad side, not the Teflon pad side making Asbestos worse than Teflon
under your theory. Also, the car will turn towards the right OR the
left when for example, the right wheel locks DEPENDING ON PAD MATERIAL
because you have dislike pads. The tires sliding on the road might
still be providing more drag than the Teflon pad at the pressure the
Asbestos pad would lock the brakes resulting in the car turning TOWARDS
the skidding tire. The car is guaranteed to turn AWAY from the
skidding tire with like pads but could go either way with dislike pads.
Dislike pads need dislike pressures to provide the same amount of
friction (achievable on an anti lock brake system which this the test
car you specifically stated is not).

Matt, I am sorry but I think you have the "coefficient of sliding
friction" partially confused. The "coefficient of sliding friction"
for two materials is the same regardless of pressure. In fact, if two
materials are not even touching their coefficient of sliding friction
is the same as if those materials are forcefully pressed together while
sliding past each other. That is not what the "coefficient of sliding
friction" is.
Sometimes I have problems articulating myself as well. Obviously,
because there are still people who disagree with me :-)
