Someone mentioned before how they did not like the looks of the Mirrors in
N4. They said it looked like they were in a fish bowl or something to that
effect.
Hit H while in the game to bring up the help menu. I think it is the N key
that turns off the interior part of your car from the mirror. This lets you
see ALOT more and it is now just a flat mirror. Kinda nice I think. It
will also give you about a whole whopping 1 FPS :)
