Have you ever taken notice which direction your windshield wipers wipe?

I know it's crazy, but, I think my windshield wipers are the only ones on the road that wipe in a crazy direction.

As I'm driving into work today, raining of course, I noticed most windshield wipers were wiping side to side.  Mine don't do that!  Mine wipe from the outside to the inside! I own a Dodge Caravan and was just curious if mine is the only car on the road that swipes from the outside to inside?  lol
