Just to answer your question earlyier in this post.. I think it was your question.. The reason they mirror one side of a skin is that whenever someone is infront of you when you are twinning and you go sideways, the right side of your car will look normal in that persons rear view mirror.. I think.. The same idea that ambulances uses.. when you have them in your rear view mirror you see "ambulance" but when you see it from infront it's mirrored..
