Abstract: The driver, in trying to manage the directional control of his vehicle, is often seen rotating his head or torso beyond 90 degrees (past perpendicular) in an effort to gain intelligence about what competing vehicles are flanking his "blindsides." Such a competing vehicle may occupy that area in the "blindside" (left, right or both sides past perpendicular) not directly observable through the rear view mirror. The requirement to make an extraordinary inspection of the vehicle "blindside" is often exacerbated by the poor design utility of the vehicle itself. Those who are physically unable to check the "blindspot" (such as the elderly) knowingly risk collision. The instant invention is the first high-technology effort to address a solution to this problem. A sequentially operating dual sensor technology is used. The first sensor effort takes place as a photonic event.
