How to judge the distance between cars for beginners?

[Kathleen]

Methods for beginners to judge the distance between cars: 1. The left one-third of the left rearview mirror and the right half of the right rearview mirror are danger zones for the following car; 2. If the following car is directly behind, when the inner rearview mirror can no longer see the wheels of the following car, it means the distance is less than 20 meters, and sudden braking should be avoided; 3. When the front of the car just touches the edge of the front car's tire, the distance should be about 5 meters; 4. When the front of the car aligns with the lower edge of the front car's bumper, the distance should be about 3 meters; 5. When the front of the car aligns with the front car's bumper, the distance should be about 1 meter; 6. If the front of the car aligns with the lower edge of the front car's license plate, the distance should be about 0.5 meters.
