There ya' go.
What does work is a deeply curved windshield. Many modern cars, e. g. Loloa T70 & etc., have it. The curved screen on a Superbeetle is good for 5mph additional top speed on the salt flats. Look at the Volkhart-Saggita for example. The cabin is almost a separate form and the cowl is kept very low so air can roll off to the sides.
