Well, that's certainly a novel thought, but totally wrong. King pin inclination only comes into consideration when turning. When going straight down the road, the king pin could be welded solid, with no effect whatever. (Just keepin' it real here...) Now wheel inclination, also known as camber, that is a different animal, and does cause the cone shape action, but that is a whole different subject, with little relation to toe.
