Abstract
The present invention is a vehicle safety rearview mirror assembly with distortion offset element and method of using the same. The rearview mirror assembly comprises an elongated convex mirror. The convex mirror is independently supported by a double-ball-joint shank and a mounting base affixed on the windshield of the vehicle. The present invention also provides a method to offset the distortion created by the convex mirror. The method combines a safety reference and a safety locker to tell the driver whether and when it is safe to change lanes or make turns. The safety reference includes two opposite end portions of the rearward visual field respectively prescribed by the side windows of the vehicle, and the safety locker includes the central portion of the extended rearward visual field respectively prescribed by the rear window of the vehicle. When another vehicle appears in the safety reference, it is not safe to change lanes or make turns; when the other vehicle appears in the safety locker, it is safe to change lanes or make turns if the front end of other vehicle is entirely visible in the safety locker because by then the distance between the driver'"'"'s vehicle and the other vehicle is farther than the nearest safety distance.
