What is the Principle of Reverse Parking?

[MacCali]

The principle of reverse parking is the three-point alignment principle. Below is a related introduction: Introduction: The three points are: the eye, a specific position on the car body, and a marker on the ground. When these three points are aligned in a straight line, the position of the car can be determined. Key Points: During reverse parking, when the car is just entering the parking space, the eye sees the lower edge of the left rearview mirror aligning with the parking line. Besides reverse parking, the three-point alignment principle is also used in the roadside parking test in Subject 3. When the car body maintains a 30cm distance from the white solid line on the roadside, the eye sees through the car window that a point on the windshield wiper aligns exactly with the roadside line. At this moment, the eye, the point on the wiper, and the roadside line form the three reference points in the three-point alignment principle.
