There is a lpt of other silly stuff, in the olden days of 1 sided cut keys, Crysler cars had the cut side up and GM the cut side down. Chrysler you cranked one way to roll the window up, gm was the opposite. It even continues to which side of the button you press for electric windows to go up or down. My best guess is a loyalty thing. Dang windows roll the wrong way, dang drivers are on the wrong side of the road.
