1. Dust - If you've been to a dirt track you know that there's a ton
of dust. Visibility should get worse as the race goes on. With the
ability to do great looking smoke in Glide, it should be fairly simple
to color it brown and make dust.
2. Mud- Having mud splatter on the windshield when running a wet
track would be super. Would really increase the immersion factor of
actually being on a dirt track.
I downloaded the demo last night and it's the most fun you can have
with your clothes on. Can't wait for the full game.
