Nowadays, more and more people have their own cars, but many people can only drive and do not understand cars. For example, the small round mirror on the rearview mirror of the car, many car owners do not know what its role is, and do not know whether there is a need to install a small round mirror on the rearview mirror. In fact, the small round mirror on the rearview mirror is very useful, and today Xiaobian will come to give you a popular science.
The car rearview mirror is a very important component of the car, which is located on the left and right sides of the car's head and in front of the car's interior. The rearview mirror is the second eye above the car, which expands the driver's field of vision, allowing the driver to observe the rear at all times. Especially in the event of rain and snow, it is convenient for the driver to observe the unexpected situation behind him, so as not to collide with other vehicles, so it is very important to learn to observe the condition through the rearview mirror.
The small round mirror above the car's rearview mirror, also known as the wide-angle mirror, is an auxiliary device on the rearview mirror, which is generally installed under the rearview mirror, which can increase the driver's viewing angle so that the driver can observe the side of the body and the rear wheels. The addition of small round mirrors can reduce the occurrence of traffic accidents, especially when overtaking and changing lanes, so that the driver can see the condition of the car clearly, so as not to collide with other vehicles.
In addition, we can usually observe the rear situation through the small round mirror when reversing, which is convenient for the driver to reverse into the warehouse. In particular, novice drivers can better grasp the road conditions when reversing and easily complete the reversing. In addition, when we drive on rough mountain roads, we can better observe the road conditions through small round mirrors to avoid friction with other vehicles.
Although there are many advantages to installing small round mirrors in car rearview mirrors, there are also some disadvantages. First of all, the deformation and distortion of the small round mirror are more serious, and we will have a rear-end accident due to misjudgment when judging the distance from the rear car. Secondly, the small circular mirror, whether mounted on the right side or above, will block part of the line of sight, resulting in us not being able to see when driving.
So should the car rearview mirror be installed at all? For car owners with poor reversing technology, it is still necessary to install small round mirrors that can help you easily reverse. However, the small round mirror can only play an auxiliary role, can not replace the rearview mirror, so we still have to observe through the rearview mirror when observing the car condition.
So how do we usually judge the distance from the rear car through the rearview mirror when driving? First of all, when the rear vehicle is located in the center of the rearview mirror, it means that the rear car and our car are still more than ten meters away, which is safer. When the rear vehicle is full of rearview mirrors, it means that we have a distance of seven or eight meters from the rear vehicle. When the rear vehicle is full of rearview mirrors, it means that the rear vehicle is still two or three meters away from us, at this time we must be careful to drive to avoid collisions with the rear car. We usually learn to judge the distance from the rear car through the rearview mirror when driving, so as to avoid rear-end accidents.
