Introduction of rearview mirror
The first car, no rearview mirror. For a long time, drivers always look at the side and rear of the vehicle by turning their heads. The first person who came up with the idea of looking around the car with a mirror was a female racing driver-Dorothy Levi. I will take out a mirror from time to time to observe the situation behind the car during the game, but I didn't fix the mirror in the car.
Later, a racing driver named Rekha Ron directly installed the mirror in the car and won the championship. But after the game, the champion complained that the mirror was shaking too much to see. It was not until 192 1 that this way of installing mirrors on cars was officially adopted by car companies. The inventor of Elmer Berger registered the patent of automobile rearview mirror, and began mass production in automobiles, and rearview mirrors began to spread gradually.
Most of the early rearview mirrors were round and flat mirrors, which were only available on the driver's side. Later, it began to evolve into a square rearview mirror and an arc rearview mirror with larger coverage. Over the years, people have become accustomed to obtaining the peripheral information such as the back, side and bottom of the car through the rearview mirror.
