I would like it so I can see a small bit of the car I'm driving, I assume that's what you mean.
Or make it so you can adjust the angle the mirrors face at.
Well, the cost in resources might affect the FPS a lot. Instead of having one rear view displayed on 2, 3 or 4 mirrors, as it is at the moment, each mirror would have to have its own view generated. It would drag lots of computers to a crawl.
yea, this has bugged me for a long time. I look in the mirror and I don't have much of an idea how far away the person is unless I turn the drivers head. but by turning the head I can't see ahead of me and that can cause a ruined race.
