How to adjust the rearview mirror so that the blind spot will be smaller?

How to adjust the rearview mirror to make the blind spot smaller? Today I will use a video to specifically talk about this. How to adjust the rearview mirror to minimize the blind area? Before adjusting the rearview mirror, be sure to adjust the height of the front and rear seats. Otherwise, the adjustment of the rearview mirror will be in vain when the seat moves. The American Society of Engineers (SAE) has a saying: The rearview mirror should be adjusted outward as much as possible to reduce the blind area caused by overlapping with the interior rearview mirror.

But don’t look too far out, otherwise you won’t be able to see the side of the car and the nearby areas. When crossing a narrow road, you won’t be able to see the battery cars, pedestrians, curbs, and obstacles next to you. Let me share a relatively reasonable method of adjusting the rearview mirror. First adjust the rearview mirror to the left: adjust the rearview mirror outward until the right edge of the rearview mirror can just see the door handle of the front door.

Then adjust the up and down angle. Generally speaking, the ratio of sky to ground is about 1:1. If the reversing distance is not well controlled, leave a little more ground. Because we usually park on the right and reverse a lot, we often need to confirm the position of the right rear wheel, so the right rearview mirror can be adjusted further toward the ground. Of course, if you have an electric car or a door handle that is hidden inside, you can just refer to this meaning, which is equivalent to "a pinch of salt".

It can be found that after this adjustment, people and cars that were originally in the blind spot can now be seen. Finally, the rearview mirror in the middle of the car. This is actually relatively simple. Just put the rear window completely in the middle of the mirror and it will be fully displayed. If it's too low and facing the back row, it won't be effective.

After adjusting the blind spot, how do you usually observe it?

After this adjustment, the blind spots on the side of the car are indeed smaller, but there are still no blind spots at all, right? Under normal circumstances, by turning our necks, we can see a field of view of about 200° in front of us. The left and right rearview mirrors on the car can each provide a field of view of about 30°. Isn’t there a blind spot of about 100° in the field of vision? That is, slightly behind the side of the car.

To be specific, when sitting in the driver's seat, the directions from 3 o'clock to 5 o'clock and 7 o'clock to 9 o'clock are actually not very visible.

We placed two ice cream buckets in the blind spots on both sides. You see, you can’t see them in the rearview mirror at all. Moreover, these two blind spots are like slices of pizza, radiating out like rays. The farther the distance, the larger the blind spot. On highways and elevated roads, this blind spot can even be so big that it can block the next car.

Also, when we turn right and want to observe the non-motorized lane, we will also be troubled by the blind spots on both sides. Therefore, when some masters are driving, when changing lanes and turning, they not only have to look at the rearview mirror, but also turn their heads directly to look in order to avoid cars in the blind spot.

And in many foreign areas, there are mandatory requirements for this when taking the driver's license test. The scientific name is called "shoulder check", and the shoulder must be over the shoulder. You can also use this technique flexibly when driving.
