How to Find the Three-Point-One-Line When Learning to Drive?
2 Answers
“Three points” refer to the driver's eyes (hereinafter referred to as the "first point"), any point on the moving car (hereinafter referred to as the "second point"), and the projection point of the ray connecting the first two points on the ground (hereinafter referred to as the "third point"). "One line" refers to the ray connecting the first two points. Additional relevant information is as follows: Note 1: According to the geometric principle that "two points determine a straight line," the second point seen by the eyes coincides with the third point. Or, what the eyes see on the ground is both the second and third points. From the stationary state of the car, the distance between the third point and the edge of the car's outline, as well as the distance to any reference object outside the car's blind spot, is fixed. This is because the driver's sitting posture in the cockpit remains largely unchanged. Note 2: When driving, whether the car can move safely depends on the safe distance between the car itself and surrounding obstacles (or the "any reference object outside the car's blind spot" mentioned above). The driver can see the distance from the second and third points to surrounding obstacles while driving, which also determines the distance between the car itself and surrounding obstacles. This provides an important reference for maintaining a safe distance between the car and surrounding obstacles.
Finding the three-point alignment is a key technique for keeping the vehicle centered in the lane while learning to drive. My driving instructor told me that first, you need to adjust the seat and mirrors properly to ensure a comfortable seating position and clear visibility. Then, keep your gaze level and focus on a distant fixed point as the first reference, such as a traffic sign or a tree at the end of the road. Next, locate the second point at about one-third of the way up the hood, which usually corresponds to the centerline of the lane. Finally, the third point is the position of the driver's eyes. While driving, align these three points in a straight line, and the car will stay steadily in the middle of the lane. During practice, stay relaxed—don’t grip the steering wheel too tightly; just hold it lightly and let your body naturally sense the movement of the vehicle. After a few practice sessions, you’ll easily develop the feel, and a quick glance will tell you if the car is veering off course.
