What are the methods to judge the distance around a car?

Methods to judge the distance around a car are: 1. When the line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will run over that object while moving; 2. When the line of sight aligns the intersection of the cotton panel and the A-pillar with the centerline, the body is 60 cm away from the centerline; 3. When the line of sight aligns the right wiper with the target, the tire will run over the target; 4. When the right washer overlaps with the roadside target, the body is still 60 cm away from the roadside; 5. Using the center of the rearview mirror as a reference line, when the body is outside the reference line and the rear vehicle cannot be fully seen, the distance is 5 meters; 6. When the rear vehicle can completely appear in the rearview mirror and the body presses on the reference line, the distance is 10 meters.
I've been driving for many years and often use the rearview mirror to judge distance: when looking back, if the car behind is centered in the mirror, it's about 5 meters away; when it's near the edge, it's only about 2 meters. When the wheels are parallel to the parking line, remember that the position where the right wheel aligns with the line is the safe distance. Also, when driving at night, the height of the headlight shadow on an obstacle can help estimate the height difference. I always practice parking in open spaces with cones, memorizing the length and width of my car. With enough practice, you naturally get a feel for it and won't scrape around. On rainy days, be extra careful—the lights can blur, so estimate the distance a bit more generously.
