The hose routing on any race car will look ghetto as f**k to anyone primarily concerned with street driving. All the duct work is is like that house-heat-duct kinda stuff, but not metal (ya know, like the tube is yellow or red cloth stuff and the "frame rings" are black). The reason they dont just vent a window is because the windows dont move- they are lexan/plexiglass/something not moveable/something not real glass. Roof scoops on front-engined cars only let air into the cabin to cool the driver (no engine benefits), and obvisouly on rear-engined cars, roof scoops duct air to the engine for either cooling or air-intake for the engine, depending on the individual configuration of the car.
