When adjusting mirrors, why is it necessary to lean over in the seat?

Leaning over in the seat when adjusting mirrors is essential because it allows you to position your head in the ideal spot for making accurate adjustments. This helps ensure that the mirrors are set to provide the best possible view of the surrounding area while driving. When the head is centered in relation to the mirrors, it facilitates a more precise alignment, maximizing visibility and reducing blind spots.

This practice is especially important for side mirrors, as they need to reflect areas that may not be directly visible from a seated position. Without leaning over or adjusting your body position, you might misjudge the angle of the mirrors, leading to inadequate visibility and increasing the risk of accidents.
