Car mirrors, history and origins
Mirrors were designed and studied in 1911, and the first person to install them on his car was pilot Ray Harron, who won a single mirror at the 500-mile Indianapolis (American automobile competition). Before that, it was a completely unknown addon.
The mirror was placed on the hood of the car and then adopted on all cars as an option before becoming mandatory on all cars. In France, it was made compulsory by decree of July 1, 1972. The car’s rear-view mirror consists of a mirror and a support that supports the small window as well as the arm.
In newer and more or less modern cars, there is also a reversing camera with a display. The center rearview mirror shows the reflected image of everything behind the car, even that caught by the camera which is especially important in the evening when the lighting is low.
