1, the difficulty is at the rear, left rear and right rear, and it is easy to qualify.

2. The parking position of the starting point and the reverse starting point is very important. The best position is to keep a distance of 1.2- 1.5 meters from the front line. The high error rate of the second fall means that it will not stop at the starting point.

3. The infrared probe in the examination room is not aimed at the widest part of the car body, and the vertical line at the widest part of the car body does not necessarily stop. I just saw the side edge line in the rearview mirror of the warehouse, especially the distance between the two bars and the five bars, without trying to correct it.

The speed at which everyone turns the steering wheel and the speed control determine the steering route of the car. Determine whether the route is getting bigger or smaller (it will hit the sidebar).
