Improving the Field of View and the Frame of Reference in Left and Right Rear View Mirrors for Passenger Motor Vehicles 940645

There have been many attempts to improve rear vision for drivers of passenger vehicles, including but not limited to the following: Periscope mirrors -- Fiber optics -- Fresnel Lenses -- variable radius mirrors, which are used to some extent in Europe but have not been approved in the United States -- Electronic devices such as TV Camera/monitor -- infrared, mini-radar -- photo cells and video micro chips. Many of these devices depend on electrical power to even be operational, and all of these devices have proved to be expensive as well as impractical and don't hold any promise for the near-term future.
