@shan2nu: agreed, but by having a different Angle Of Attack (AOA) for each slab of glass, the aerodynamic properties change.
i was saying that if you have 2 slabs of glass with exactly the same properties except for one being double the size of the other, the drag of the larger glass will not be double, but 4 times greater.

I replied to your post bcoz you said that drag was directly proportionate to the square of the surface area its acting on.
U had not taken into account the AOA and COD of varying surfaces with identical surface areas.
So just as in this case, traction is also not entirely dependant on contact area. Quote:
I know man....
I was considering test conditions, where everything except for the contact area between the tyre and the test surface changes.

Within ideal lab conditions, it should work, but theres no saying how things will work out in the real world.
This is similar to driving a car with 5 star safety ratings, that were tested under ideal conditions in a lab at a specific vehicle speed. For all you know, you might have a small crash but a metal/glass part from the other car might fly in through the window and hit you.
All these lab tests are only applicable under certain circumstances.
