This is the rear view mirror used by police officers and professional racecar drivers to reduce blind spots. The patented, seamless mirror has a 180° field of view (standard interior and exterior mirrors combined offer only 52°) that provides a distortion-free reflection of rear traffic across an entire five-lane highway. This panoramic view allows the driver to continuously monitor adjacent vehicles when merging or changing lanes without turning his or her head. The mirror automatically reduces the headlight glare of trailing vehicles by 50% and clamps over most standard rear view mirrors without requiring tools or adhesives. The mirror is adjustable from 2" H to 3 1/4" H to fit most standard rear-view mirrors.
