How to Determine the Rear Position of the Car Using Side Mirrors?

[Terri]

The entire rear of the car cannot be seen in the side mirrors; you can only estimate the distance between the rear of your car and objects behind it. When reversing, if you see another car in the side mirror, the following scenarios apply: 1. Scenario One: When the rear car occupies the entire mirror, the distance is approximately 3 meters. 2. Scenario Two: When the rear car occupies two-thirds of the mirror, the distance is approximately 5 meters. 3. Scenario Three: When the rear car occupies half of the mirror, the distance is approximately 9 meters. 4. Scenario Four: When the rear car occupies one-third of the mirror, the distance is approximately 12 meters. Another simple method: Place a reference object 10 meters behind the car, ensuring it is at the same level as the side of the car; otherwise, it won't be visible in the mirror. Then, get into the car and observe the position of the reference object in the mirror to gauge where the 10-meter distance roughly corresponds in the mirror.
