.

	Air_resistance = Frontal_area * Drag_coefficient

Another fav equation of mine, tho not recognized by the SAE, is:

	Estimated_speed = Actual_speed * Size_coefficient

Where Size_coefficient for various vehicles is as follows:

	18-wheeler		5.54
	Cadillac		2.32
	Volkswagen		0.64
	motorcycle		0.23
