How to Judge the Distance to Vehicles on the Left, Right, Front, and Rear While Driving

[StFrank]

Methods to judge the distance to vehicles on the left, right, front, and rear while driving: The distance to the rear vehicle can be estimated based on the size of the vehicle's reflection in the rearview mirror. When the reflection occupies the entire mirror, the distance is 3 meters; when it occupies two-thirds of the mirror, the distance is 5 meters; when it occupies half of the mirror, the distance is 9 meters; and when it occupies one-third of the mirror, the distance is 12 meters. The distance to the front vehicle can be determined by observing the position of the rear bumper and tires of the front vehicle from the contour line of your own car's front. When the upper edge of the front vehicle's rear bumper is visible, the distance is 1 meter; when the lower edge of the rear bumper is visible, the distance is 2 meters; and when the lower edge of the rear tires is visible, the distance is 3 meters.
