Physics 103 - If (or when) a car gets turned backwards at 175 mph, the rear window (along with the roof flaps) creates downforce which helps to keep the car from going airborne. If the rear window was not there, the roof would act as a lift, turning the car into an uncontrolled missle.
They could louver the back window opening in such a way that it would slam shut when the car got turned around and/or install more flaps in the roof.
