I feel that the outside mirrors of the car are pointing too much to the outside. And therefor you can't directly see cars that are near your door. So what I am trying to say is, irl my own cars outside mirrors are pointed in a way where I can see the side of my own car, but just barely. Resulting that if some one is door banging me I will be able to see it in my mirrors. Does any one know what I mean.
I can't remember and am not near an active r3e/rf2 session but one of them lets you use the left control key and your seat back button and the right control key and seat forward button to change side mirror positions. Hope it was r3e for you.
