I have no proof that fins on a car works, if they do then all those cars including concept cars from the 1950's - 1960's were not so silly after all.
I could not find a good Kammback diagram or wind tunnel snapshot showing the flow over the roof.
Won't any large flat-ish plane cause air to roll over it sideways and then start forming a vortex as it leaves the corner/edges?
