What really? I find the side mirrors and the backup cam 10X better for lining up the car perfectly than doing the oldschool look-over-shoulder arm-over passenger seat thing. Especially since the backup cam doesn't change in perspective as I crane my head to get the side of the car in view in the sideview mirrors.
