Does the left rearview mirror show only what's on the left side?

The left rearview mirror is used to view the two lanes to the left of your vehicle, the right rearview mirror is for the two lanes to the right of your vehicle, and the center rearview mirror is for the lane directly behind you. Relevant information about the rearview mirror heating function is as follows: 1. Identification: The rearview mirror heating symbol is a curved upward arrow paired with a rectangular pattern. The location of the rearview mirror heating switch varies by vehicle model, but the symbols are generally similar. 2. Working principle: An electric heating element (heating film) is installed inside the mirror lenses of both side rearview mirrors. In rainy or snowy weather, when the driver activates the rearview mirror heating function, the heating element quickly warms up to a fixed temperature within a few minutes, typically between 35-60 degrees Celsius, thereby heating the mirror surface to remove fog and frost.
I've been driving for nearly twenty years, and this question comes up frequently. Looking through the left side mirror, it does display most objects on the left side, such as vehicles behind or the road edge. However, there's a significant blind spot near the rear of the car, especially at high speeds when another vehicle might lurk just outside the mirror's angle. Once, I almost sideswiped a motorcycle when changing lanes because I relied solely on the mirror without looking over my shoulder. Now, before every drive, I make it a habit to adjust the mirror: first, I park the car straight, then adjust the mirror so it shows an extended line covering the left lane and a slight glimpse of my own car body to avoid missing anything too far out. In daily driving, you can't depend solely on mirrors; always turn your head to check blind spots before changing lanes to prevent sudden incidents. Especially in rainy, foggy, or nighttime conditions with poor visibility, keep mirrors clean and clear to minimize misjudgments. Remember, safe driving involves integrating multiple observation points, including other rearview mirrors and forward visibility, ensuring comprehensive control.
As someone concerned about road safety, I must emphasize that the left rearview mirror primarily captures information from the left side, but it is not omnipotent and is limited by angles and positioning. The mirror typically covers a field of view of about 45 degrees, but the vehicle body itself can block adjacent areas, creating blind spots. For example, motorcycles or rapidly approaching vehicles may become invisible if they are at a corner. The key to safety lies in developing standard operating procedures: before changing lanes, signal first, then check the left rearview mirror to confirm a wide range, followed by turning your head to scan the blind spot for at least one second before taking action. It's best to adjust the mirror while stationary, aligning the mirror's edge with the lane line to expand the visual range. If the mirror is aging, blurry, or the adjustment screws are loose, it may distort or miss details, requiring regular maintenance. Additionally, on curved roads, the mirror's field of view is even more limited, making it crucial to maintain a moderate speed to increase reaction time.
