How to accurately judge the distance between left and right front and rear?

Everyone knows that driving is easy, but driving a good car is difficult. At driving school, all we learn is a few superficial things, just another kind of test-taking education that allows you to quickly pass the test and get a driver's license. True driving skills and experience are learned over time.

First of all, how to judge the distance between the left and right front and rear? It can be judged by the position of the revolver. We need to know where the revolver will be pressed to avoid the tires pressing against solid lines, or avoiding potholes and stones on the road. In addition, friends need to know that it is safest when we are driving 60 cm away from the center line.

Generally, when our line of sight coincides with the intersection and the middle line of the cotton board and the a-column, the body is basically in the position of 60 cm. Also, if our line of sight crosses the right wiper with a target, the tire will press over that target. When the right sprinkler overlaps with the roadside target, then at this time the body is 60 cm away from the roadside.

Judge the distance between the front end of the car and the person:

Taking a sedan as an example, suppose there is a person in front of you who is about 1.7 to 1.8 meters tall, with a foot height of about 10 centimeters, a knee height of about 45 centimeters, and a hip height of about 70 centimeters.

1. When you see the front end of the car moving from the ground to the human body or the heel and staying here, the distance between the front end of the car and the human body is 3 meters.

2. When you see the front end of the car rise to the height of the human knee, the distance between the front end of the car and the human body is 1 meter.

3. When you see the front end of the car rising to the lower end of the human hip, the distance between the front end of the car and the human body is 0.3 meters. Judge the distance in front of the car:

1. From the lower edge of the windshield, it is about one meter when you see the upper edge of the bumper in front of you;

2. About two meters when the lower edge of the front bumper is seen from the lower edge of the windshield (the knee of the person's foot);

3. About three meters when the lower edge of the front and rear tires are seen from the lower edge of the windshield (or when the ground is seen);

4. The horizontal line opposite the ground seen at the lower edge of the left rearview mirror is the front position of the car.

The right rearview mirror determines the distance behind the car:

1. When the rear car shadow occupies all the rearview mirrors, the distance between the vehicles is about 3 meters;

2. When the rear car shadow accounts for two-thirds of the rearview mirror, the distance is about 5 meters;

3. When the rear car shadow accounts for one-half of the rearview mirror, the distance between the vehicles is about 9 meters;

4. When the rear car shadow accounts for one-third of the rearview mirror, the distance is about 12 meters;

5. The left rearview mirror sees the rear wheel cover in the middle (rear door handle, body cross line or rearview mirror bottom line reflection) opposite the ground is the rear position.

6. Judge the distance of the rear car through the lower edge of the rear window windshield through the rearview mirror: if you see the upper edge of the rear headlights, the rear trunk is about three and a half meters from the rear car; If you see the junction between the rear car compartment cover and the front retainer, the rear tail box is one meter away from the rear car; If you see a third of the level of the front windshield of the rear car, you are basically leaning up.

Determine the vehicle position (wheel position, front and rear position):

1. Judge the position of the roadside in the windshield (the left wheel is 10-15cm to the right of the left column of the windshield; The right wheel is 5-10 cm to the left at the centerline of the windshield); The distance from the curb can be seen in the rearview mirror.

2. Judge the right wheel position (middle of the front or right wiper): the opposite ground in one-third of the right side of the front cover.
