What is the approximate distance of 30 centimeters in the rearview mirror?
2 Answers
30 centimeters in the rearview mirror is approximately the width of two fingers. The functions and adjustment methods of the rearview mirror are as follows: Functions of the rearview mirror: The rearview mirror is a tool that allows the driver to directly obtain external information about the rear, sides, and lower parts of the car while seated in the driver's seat. For the convenience of the driver's operation, to prevent traffic safety accidents and ensure personal safety, all countries require that cars must be equipped with rearview mirrors, and all rearview mirrors must be adjustable in direction. Rearview mirror adjustment methods: For the right rearview mirror, adjust the horizontal line to the middle line of the rearview mirror, then adjust the edge of the car to occupy one-fourth of the mirror surface. The parallel horizontal line can be adjusted to the middle position of the central rearview mirror, and then move left and right to place the right image on the left side of the mirror surface.
As a seasoned driver with over a decade of experience behind the wheel, I've long noticed that judging distances through rearview mirrors always has discrepancies, especially for close ranges like 30 centimeters. The curved nature of the mirrors makes objects appear closer than they actually are. For instance, when reversing in parking lots, I sometimes estimate an object to be about 30 centimeters away based on the mirror, only to step out and find it's actually more than 60 centimeters away. On slopes, a slight miscalculation could easily lead to a scrape. That's why I've developed the habit of not relying solely on rearview mirrors when parking—I also lean out to check or use the parking sensors for confirmation. For new drivers, I'd recommend practicing more in open areas to hone your judgment skills. This not only makes driving safer but also gives you greater peace of mind.
