How much damage does installing a rearview radar cause to the original car?

[MarcusFitz]

Installing a rearview radar can cause significant damage to the original car. Below is an introduction to precautions when reversing: Reversing method: Before reversing, first check the situation behind the car, estimate the path of movement, and ensure that the front of the car will not hit any obstacles. Try to avoid stepping on the accelerator when reversing, and control the speed to avoid going too fast. Depending on the direction the rear of the car needs to move, use the left hand to turn the steering wheel. If the rear needs to move to the right rear, turn the steering wheel to the right. Conversely, turn the steering wheel to the left. Precautions: During the reversing process, do not keep looking at the rear. While ensuring the safety behind the car, it is necessary to occasionally observe the left and right rearview mirrors, pay attention to the distance between obstacles and the car body, and accordingly use the steering wheel to adjust the position of the car while reversing. If you feel that the front of the car might hit an obstacle during reversing, you should also check the front of the car at the appropriate time.
