Many people will Xi leaving a quarter of the area for their body when adjusting the exterior mirror, because it is the most comfortable to look at.
However, there are also objections to this, on the grounds that the rearview mirror has a limited field of vision, and it is a waste of resources to let the rearview mirror shine on its own body. They don't think they need to see their body in the mirror, so they can turn the mirror as far out as possible to accommodate more vision on both sides of the car and reduce blind spots.
In fact, I don't think there is a completely correct standard for how to adjust the rearview mirror, it depends more on personal Xi. But for novice drivers, I think it's still very necessary to see part of the body in the rearview mirror.
1. Many people don't notice that the body that appears in the rearview mirror is a very good reference.
On the premise of seeing the body, you can more accurately determine the distance, relative position and relative speed of other vehicles, pedestrians, and obstacles to your vehicle. Not only is this safer, but it also helps newbies develop their driving skills faster.
And if you can only see other vehicles in the rearview mirror, it will be more difficult for you to judge the distance and relative speed between you when you are not too far away, which is actually more dangerous. You can compare the upper and lower pictures to see if you feel this way.
2. Being able to see your body in the rearview mirror is also a reference for you to check whether the angle of the rearview mirror is correct.
Because sometimes your rearview mirror can be touched by someone else, such as when a worker wipes the lenses during a car wash, the angle of the lens may change. If you adjust the angle to see the body, then you can easily spot and adjust back the lens angle as soon as possible.
But when you can't see the body in the rearview mirror, if the lens angle has changed a little outward, it is difficult for you to find the problem in time, at this time, the rearview mirror field of view has changed, and the blind spot near the body area increases, especially when you stop and open the door, you are likely to not see the approaching bicycle, and the safety hazard will be greatly increased.
For veteran drivers, their car feeling is good enough, so whether the body appears in the rearview mirror or not depends entirely on personal preference. But for beginners, we are in the Xi learning stage, and it is more advantageous to have a part of the body in the rearview mirror.
Some tips for using the rearview mirror:
When the car turns and when changing lanes, the angle of the vehicle changes, and as the body turns, the view of the rearview mirror sweeps a fairly wide area behind it. At this point, your rearview mirror is like a radar and you can see more information. So don't waste this opportunity to fully observe the road conditions behind you when changing lanes and turning.
Every car has an interior mirror, located in the center of the cab, which is very helpful for grasping the road conditions behind you. I usually tend to tilt the mirror slightly to the right so that it shines on both the rear of the car and the right side of the car, which further reduces the blind spot on the right side. The left side of the body is much more convenient to observe, and it is enough to turn your head more on your own. However, it also depends on the angle of the windows, and some cars have a central rearview mirror
There are two issues that I think it is necessary to state with you:
First of all, it is not necessary to have most of the body in the rearview mirror, as it is said on the Internet that "the body occupies a quarter of the view of the rearview mirror". I think it's good to be able to see a little bit and use it as a reference. Too much of the body in the rearview mirror is just a waste, and it does add to the blind spot on the side of the body.
Secondly, you should never expect the rearview mirror to be adjusted to an angle with no blind spots, after all, how much information can you expect it to provide you in a palm-sized place? The rearview mirror is a reference, and if you really want to fully grasp the situation in the rear, you must cooperate with the head twisting to observe, after all, what you see with your own eyes is the most reliable.
