I agree, the car looks more slick and streamline without a wiper. Rain repellent works wonders at clearing the glass above a certain speed. I always carry a window squeegee in the car for any eventuality that the rear screen may need a quick clean..
I have it optioned on mine..... Aesthetically yes, it does look better without but i will never be looking at it! So I thought i might as well if it does improve visibility..... As others have said, it could be removed and blanked off if i dislike that much if my Macan ever arrives!
got it too.
Its a very personal choice.
rear window is very small anyway, so you dont see much through it, window clean or not.
I got my car 1.5 month ago and personnally like the wiper on it (black turbo), it breaks the swept back look of the line; but again its personnal.
Operationally speaking:
window is so small, wiper is not of a big help.
but dont forget the rear camera is back from the 90's, the way it works,
