*The radiator cap,it's excrescence,spare tires,4-mirrors,upright windscreen and A-pillars are going to compromise the side flow along the greenhouse.
*If the flow is intact longer along the top due to the taper it won't see the full benefit because the side turbulence and it's low pressure which may cause downward bleeding and vorticity.
*It IS and abomination.Highly mutilated!
