ABSTRACT:
A system to overcome the visual aberration of spherical automotive rear view mirrors, related to the distance between vehicles, requires no measurement or mathematical skills. The system includes means for visually determining the curvature of a mirror, and templates for the proper placement of etched film strips which frame a safe return target area on the mirror. This target area is an indicator of when a vehicle seen in the mirror is at a safe distance behind the vehicle with the marked mirror.
