It would be nice to be able to change the view of the two side virtual mirrors to show the view 90degrees to the side of the car so you could easily see if an opponent was alongside while driving in cockpit view.
When at it - it must be more intuitive to control the mirrors. Using the key shortcuts just isn't intuitive enough, IMHO, I really can't remember which key do what... Maybe an extra LCD (black box) could ease these - navigate up down to choose mirror/parameter to adjust, and left right to decrease/increase those (at least yaw and pitch, and maybe also mirror FOV).
