The rearview mirror is an important component of a car, and many driving skills we learn in driving school require it. Moreover, in daily life, the role of the rearview mirror is irreplaceable. However, the news of electronic camera rearview mirrors replacing traditional rearview mirrors has been around for a long time, and countries such as Japan have legislated to support it. Lexus ES also planned to launch a new car without rearview mirrors. So what are the benefits of replacing traditional rearview mirrors with cameras? Is it really feasible?

The benefits of electronic camera rearview mirrors:

1. Reduced wind resistance. The design of a car needs to consider the issue of wind resistance, but due to some safety considerations, this design is not perfect. The rearview mirror can increase wind resistance by nearly 6%, which is not a small number. If replaced with electronic rearview mirrors, wind resistance will be greatly reduced, and fuel consumption will naturally decrease.

2. Capable of handling various weather conditions. In rainy days, the driver's vision will be reduced, and the rear view mirror is easily blocked by raindrops. Although the rear view mirror is heated, it is still not applicable in rainstorm weather. The impact on electronic rearview mirrors is minimal, and rainy and foggy weather can provide better visibility.

3. A broader perspective. Electronic cameras can provide car owners with a wider field of view through wide-angle cameras, and unique algorithms can also bring clearer feelings to car owners.

So are electronic rearview mirrors all advantages? In fact, the United States explicitly prohibits its use. Electronic rearview mirrors, due to current technological limitations, provide "degraded image quality" and cannot provide true feedback to car owners as traditional rearview mirrors do. Moreover, the display screen of the electronic rearview mirror can easily cause visual fatigue to car owners. There are already enough screens available now, and adding two more would be a bit uncomfortable.

Overall, although electronic camera rearview mirrors have their drawbacks, they have more advantages. With technological advancements in the future, it is really possible to completely replace traditional rearview mirrors.
