Why do the left and right rearview mirrors of a car look different?

With the continuous improvement of life, there are more and more private cars on the road, especially SUVs, MPVs, and many brands of cars, such as Honda, Toyota, etc. The rearview mirror of the car is an important part of the car, the driver needs to use the rearview mirror when driving, observe the condition of the rear of the car, once there is a situation, you can adjust it in time, but after driving the car for so many years, why do the two rearview mirrors of the car look different, always one big and one small?

In the eyes of ordinary people, the car is a symmetrical whole, the left and right sides of the things, should be the same and show an axisymmetric distribution, the rearview mirror of the car is habitually called the ears of the car, logically speaking, the left and right sides are the same, but in fact, when the car leaves the factory, the rearview mirror on the left and right sides is different, always the left side is larger, the right side is smaller, so what is the reason?

In fact, this has to start from the driving habits of the Chinese people, because according to the laws of the country, the steering wheel of the motor vehicle is located on the left side of the cab, the purpose of this is to make the car as far as possible to drive on the right, but there will be a problem, the driver is located on the left side of the car when driving, so that the visual distance between the two eyes on the left and right sides of the car is not the same.

Therefore, it is easy to make errors at the moment of driving, which eventually leads to car accidents, so the cars produced in China, the left side of the rearview mirror is obviously larger than the right side, the fundamental purpose is to make the left side of the mirror larger, the smaller the curvature, so that the left side of the field of view is smaller, the curvature is increased, so that the right side of the field of view will increase.

In this way, it will make the driver's left and right sides of the field of vision basically the same, when the car is driving, there will be no big problem because of the error of observation, of course, many Western countries are located on the right side, then when the car is produced and designed, the situation will be reversed, the rearview mirror of the car is an important part of the car, although the size of the left and right sides is different, it will be slightly inappropriate in terms of aesthetics, but this can better ensure the safety of the owner, in fact, it is very necessary.
