Remember,these are race cars! Their windshields are inside the wake area of the fender-top extractors.In inclement weather,there will be quite a rooster-tail of rain water exploding out the top of those fenders.If it doesn't destroy your vision,it may not be the same for those following in traffic.Also,you may completely destroy the airflow in that area.GTP cars can have drag coefficients like Cd 0.7!!!!!!!!! They're way cool at the track,and they need a lot of brake cooling coming off a straightaway into the first curve.Not the sort of thing we'll be doing on daily commutes.
