In "open air" it really doesn't matter, as the DF the car sees is through the mounting points to the chassis (usually through the nose) of the wing. It is the same force whether it's coming from the left or the right, with a slight difference in a dual mount (F1 style) due to the "leverage" of the two mounting points.
However following a car is the main reason you alter the wings in the front. Typically the inside wing is of a higher angle so that the driver can select a line inside of the car ahead and put air on at least one of his wings.
