Nowadays, almost all cars are equipped with a reversing camera, but when I was a child, the technology was not so high-end, and I often saw adults turning their heads to look at the distance behind when reversing, and then there was a reversing radar, which will alert you when you are approaching an object, but if you need to see what is behind you, you still need to use the rearview mirror.
With the reversing camera, don't you need to look in the rearview mirror? Some people are used to looking in the rearview mirror, is there no need to install the reversing image?
Indeed, the invention of the reversing image has made the difficult problem of reversing simple, and the objects and distances behind the car can be accurately seen through the image on the car, and the rearview mirror can be seen. In particular, many drivers will have the habit of turning their heads to look, which may cause danger in the process of looking behind, so the role of the reversing image is still very large.

But since it is an electronic device, there is a problem, if you only rely on the reversing image, what if it breaks down one day? In addition, the reversing image camera also has blind spots, and some reversing images are installed on the rearview mirror in the car, which also affects the owner's line of sight.
Therefore, if you want to have first-class reversing technology, it is better to exercise your ability to look at the rearview mirror and reverse, practice the ability to judge the distance between cars, and use the reversing image as an auxiliary means in the actual operation process.
