How to adjust the marking line in the reversing image that deviates from the center?

Keeping the car moving slowly in the middle of the lane without deviation is to pull a straight line. When moving forward, keep your eyes far away and observe the changes of window sideline and ground sideline from the corner. Look at the rearview mirror when reversing and keep the car body parallel to the sideline.

Look at the rearview mirror to distinguish the margin.

This coach should not have said that when you see the car body parallel to the sideline, the rear of the car will be narrower. When you see that the left and right margins are equal, the right margin will look a little narrower, which is the problem of poor vision in the rearview mirror. So after the car was put into storage, the students got on and off to observe and compare.

The extended data green line value is about 2 meters away from the car, so you can continue to reverse. You can safely and boldly reverse your car without entering the green line area. The actual distance between the green line and the yellow line is between 1-2 meters, that is, the yellow line tells us that our car is still 1 meter away from the object, and the area between yellow and red is 30 cm to 1 meter. The speed of reversing at this time.

Once you reach the red line, you should stop. If an alarm radar is installed, a rapid alarm will be sounded at this time, and the car will be close to the obstacle, and a collision may occur when reversing. Some reversing images are marked with "STOP" in English on the red line, requiring immediate parking.
