That's not quantum, but relativity. The light from in back of you coming toward the rear view mirror would not catch up to it. BTW if you were travelling faster than light, in your rest from your mass would be an imaginary number, a multiple of $$\sqrt{-1}$$. So I don't think you would be worrying about mirrors!
