Single centered windshield wiper?
Some European BMW's and Benzs have that same setup the CRXs have a conversion kit that makes it this way they are Fake and the position you see in the pics is just the stopped position for that wiper kit these are called INDY Formula 1 wiper kits
That CRX actually has a stock wiper. It was just taken off and put on the wiper motor splines in a different position. But this is not safe because it does not clear the water where the drivers field of vision is.
