Be sure to set rear view as rear view and NOT look back or you will be looking through the car body on the ground effect cam.

it's not that my friend. when I look back it works ok. The mirrors on the side of the car are problem.they are blank.it's tough to drive with cockpit view, when you cant see if someone else is getting near you in corners. that's my problem.
