I believe the spray behind the race car is lifted up to the area of lower pressure created by the negative AoA of the aerofoil.Well no **** sherlock. !And wot creats this low pressure area?Simple law of phisics; the resultant force of airodynamic drag acts in a direction exactly opposit to direction the object is traveling.And airodynamic deflection acts in any direction other than opposit to direction the object is traveling.Rotor blades, wings, HSs, rudders and slopen windscreens all deflect air.And the reaction of all the above is a force in the opposit direction to the deflection.
