Precautions for using automotive radar.
Reversing can be divided into straight-line reversing and steering reversing. Due to the limitation of sight, you can't see the road behind the car clearly, and there are many blind spots in the reversing radar, so you can't blindly believe it. Therefore, if you want to reverse safely, you must master some correct methods.
First of all, before reversing, whether or not the reversing radar is installed, you'd better get off and look at the rear and left and right sides of the car, especially pay attention to some obstacles such as big stones, steel pipes, fire hydrants and water pipes, and pay more attention to whether there are ditches and rivers behind the car, which is more dangerous. Secondly, when reversing, you should keep turning your head back and forth and observe it back and forth.
