I don't like the look-left/right buttons as they are now. I'm afraid to lose control of the car while my whole world is shifting sideways.
But couldn't these buttons act on the contents of the inside mirror, instead of on the whole view? Then I could still see what is happening in front of me.
So, for example, when you press the "look right" button, the inside (virtual) mirror switches its display, and shows what you'd see IRL when looking in the right-hand-side mirror. That would be a proper simulation of using your real-life mirrors, without the fps price of having 3 mirrors simultaneously.
