That's what I thought at first too. The more I've read about aerodynamics though, they do seem like they would cause the wind to change pressure gradients a little as they come around the sides, go under the front, and come up from underneath the rear. I doubt it is enough to do that much, but there are studies that show tiny little zig zag like stickers do change the wind coming off the surface.
A lot of people don't like the ones on the corners and mod them out with new body panels. The Matrix never had them and have always had the smooth look. They are removed in the 2009 Vibe model now.
I dunno, it just made me think as I was looking at my pics when posting them up.
