How can beginners judge the distance from the front of the car?

[VonEloise]

When you can see the upper edge of the rear bumper of the car in front, the distance is approximately 1 meter; when you can see the lower edge of the rear bumper, the distance is about 2 meters; and when you can see the bottom of the rear tires, the distance is around 3 meters. Here are some methods to judge the distance from the front of the car: 1. Imagine a person about 1.7 to 1.8 meters tall, with the top of the feet about 10 cm high, the knees about 45 cm high, and the bottom of the hips about 70 cm high. 2. When you see the front of the car moving upward from the ground to the person's feet or heels and stopping there, the distance between the front of the car and the person is about 3 meters. 3. When the front of the car rises to the height of the person's knees (i.e., you can see the knees), the distance is approximately 2 meters. 4. When the front or sides of the car rise to the bottom of the person's hips, the distance between the front of the car and the person is about 0.3 meters.
