What are the methods for judging front, rear, left, and right distances while driving?

When driving, it is necessary to know the position of the car on the road, how far the body is from the boundary line, and how far it is from the center line. Here are some methods for judging distances: Judging the position of the left wheel: To judge the position of the left wheel, you need to know where the left wheel will pass over to avoid the tire pressing on the solid line or avoiding potholes and rocks on the road. Judging the position of the right wheel: When judging the position of the right wheel, when the line of sight intersects with the target through the right wiper, the tire will pass over that target. Center line: Driving 60 cm from the center line is relatively safe during normal driving. When the line of sight coincides with the center line through the intersection of the panel and the A-pillar, the body is exactly about 60 cm from the center line. Parking by the side: When parking on the right side, when the node of the right wiper coincides with the roadside, slightly pulling the steering wheel to the left can achieve the effect of parking 10 cm from the roadside.
I mainly rely on habitual reference points to judge the distances around my car while driving. For the distance in front, I usually observe the relationship between the hood and the rear of the vehicle ahead. If I can clearly see the full shape of the taillights or the lower part of the bumper, it indicates a relatively safe distance of about two meters. For judging the distances on the left and right, I adjust the side mirrors so that only a small portion of my car is visible, roughly one-third, which helps me better perceive the size changes of objects on the side of the road. For the rear, I use both the side mirrors and the center mirror, paying attention to the brightness of the taillights or changes in the size of the vehicle to estimate the distance. During rainy days or at night, dim lighting can affect judgment, so I increase the safety gap and frequently check blind spots. Overall, it requires practice, such as repeatedly backing up and parking in a parking lot to familiarize myself with my car's dimensions and feel, avoiding blind spot misconceptions.
