Since 0.5 Alpha through 0.77 Beta still that visual "mistake". Have you ever been in real car? I hope yes, because reflection in ARMA III cars isn't a reflection. It is just camera-screen system, which don`t reflect, it "broadcast" image from camera to glass surface. Image should be flip vertically to looks correctly.*
Images attached.
