Having reviewed the subject of mirror adjustment, I have come up with conclusions:

1. The mirror adjustment as shown in the article -- is correct. The explained manner of adjustment -- wrong. The original adjustment is done as I have formerly mentioned: A Person standing a few metres behind the car's corner should be seen at both the outisde edge of the center mirror and the inside edge of the respective side mirror. In any cars, this means the mirrors are adjusted like explained in the article. In others -- not nessecarily.

2. With this setting we have a slight overlap between three fields of vision: The rearview mirror, the side mirrors and the peripheral vision of the driver when he looks to the side mirrors. This way, even if the rearview window is not fully seen (due to tall persons seating behind, etc...) or when the peripheral vision is narrow or the rearview mirror is somewhat neglected, the driver still has no blindspots ore atleast a minimum of them.

3. This mirror adjustment eliminates blindspots so that no car or bike can fully dissappear. Althogh the sides of the car are not seen, a scooter or bicycle cannot dissapear in the area not covered. The side of the car is only nessecary in very tight situations of parking, in which case the driver can lean his head over/readjust the mirrors/use mounted convex mirrors. We obviously drive forward more than we do backwards, and the speed, traffic and hazards involved in driving forward are greater, thus we will not adjust our mirrors in a manner than serves us while parking, but works poorly on the highway!

4. Another claim I have heard about adjusting your mirrors more closely is that the tail is used as a reference point should the mirror be knocked out of adjustment. However, with mirrors set this way, the driver can check the adjustment easily in several ways:

The first, to see when the edges of the car come into view: In most American cars, the edge of the car is only seen when the head is leaned against the glass/center of your car as described above. Second, to see how cars and bikes in traffic go around us without losing eye contact through the mirrors.

5. With this mirror adjustment, there is no point in looking over your shoulder and behind. By peeking towards your mirrors or by leaning your head slightly sideways, you recieve the nessecary information. A shoulder peek to the side, rather than a shoulder check behind.
