To what extent should the rearview mirror be adjusted for optimal positioning?

The rearview mirror should be adjusted to the following positions: 1. The central rearview mirror should be adjusted so that the left edge of the mirror just cuts off the right ear of the driver's reflection in the mirror; 2. The left rearview mirror should be adjusted so that the distant horizon is centered, and the left-right position should be adjusted so that the car body occupies one-fourth of the mirror's surface; 3. The right rearview mirror should be adjusted so that the upper and lower positions occupy two-thirds of the mirror's surface. Relevant information about the rearview mirror is as follows: 1. Introduction: The car rearview mirror is located on the left and right sides of the car's front and the front of the car body, and it is an important safety component. 2. Function: Its function is to allow the driver to indirectly see the conditions behind, beside, and below the car, thereby expanding the driver's field of vision.
I always pay special attention to the balance of visibility when adjusting the rearview mirrors. The left mirror should show a bit of my own car body, occupying about a quarter of the mirror, so I can gauge the distance. The right mirror should show even less of the car body, roughly one-fifth, because the blind spot on the right side is larger. The ideal ratio between the sky and the ground is half and half. If it's too high, you won't see the ground markings; if it's too low, it's hard to spot approaching vehicles from behind. After adjusting, always test it by actually reversing—you should be able to see both rear wheels from the driver's seat for it to be properly set. I recommend making fine adjustments after parking, not while driving, as that's too dangerous. If you switch to a different car model, readjust the mirrors, as the seat height can vary significantly.
