2. Adjustment method of the right rearview mirror: place the horizontal line at two thirds of the rearview mirror, and then adjust the edge position of the car body to occupy a quarter of the mirror image.
3. Adjustment method of the central rearview mirror: put the horizontal position in the middle and the ear position on the left. The center line of the rearview mirror is the horizontal line in the distance, then move left and right, and the image of your right ear is just at the left edge of the mirror.

Disadvantages of rearview mirror:
First, the blind area is large.
Limited by the mirror area and adjustment angle, the field of view is not wide; Some models that do well in vision, such as Subaru Forester and Honda Fit, try to improve the driver's vision by "slimming" ABC columns and matching larger rearview mirrors.
For example, the double curvature mirror technology can eliminate the blind area when turning and double the field of vision; Anti-glare technology can reduce the influence of strong light from the back car on the driver's line of sight when driving at night. Even if automobile manufacturers add many new technologies to rearview mirrors and constantly improve the blind area of sight, the shortcomings of rearview mirrors can not be ignored.
For example, sometimes it will block part of the lateral line of sight; Encountering a car in a narrow road section, reversing into the warehouse, or even entering the automatic car washing area may damage the rearview mirror.
Second, the wind resistance is large.
There is a technical term for the wind resistance of automobiles called wind resistance coefficient. The drag coefficient of a car is about 0.3, and the drag coefficient of a car can be as low as 0.23. The influence of rearview mirror on wind resistance coefficient can reach 0.0 1 to 0.03, which actually has a great influence on wind resistance.
If the rearview mirror is removed, the vehicle can reduce a lot of air resistance, and the rearview mirrors erected on both sides of the front window widen the front area of the vehicle. Two seemingly small lenses will actually increase the air resistance by 3% ~ 6%. Removing them will reduce resistance, which is equivalent to lowering the roof by half an inch. Because the air resistance of the car is reduced, the drag coefficient helps to reduce fuel consumption, and the wind noise at high speed is also reduced.
