What are the techniques for judging distance while driving?

[OJuliet]

Here are specific techniques for judging distance while driving: 1. Using fixed reference points on the vehicle: When the midpoint of the vehicle's left rearview mirror aligns with the left sideline, the distance between the vehicle and the sideline is 1.5 meters. When the first wiper node of the vehicle is on the left sideline, the left wheel of the vehicle is pressing on the sideline. 2. Judging by the position of the white line: When the white line is at the midpoint of the engine hood, the right wheel of the vehicle is already on the line. When the white line is at the halfway point on the right side of the engine hood, the vehicle is 30 centimeters away from the right sideline. When the white line is at the one-third point on the right side of the engine hood, the vehicle is 60 centimeters away from the right sideline.
