Mine has rain guards like this. The Impreza has frameless doors, so the vents go over the front and rear doors. They're not very big, but they do push a lot of air at the A-posts.

Hey, now that I'm thinking about it...why don't you guys uses roof rails like the land speed cars use?

I'm mostly talking about the 1/2" aluminum strips that screw to the rain gutters on the roof. Some cars (like old BMW racecars) also use fences on the edge of the hood. You could also mount some on the A-posts of some cars if you wanted. The path OVER the car is one of the smoothest so keep the air up there, not the turbulent sides.

I usually run with my drivers window down a few inches, except in winter. I wont run with the front passenger side window open that much, or Ill get blasted by crosswinds. But if I open the passenger side rear window about that much, it cools the car better than anything and doesnt blast me.
