The interior rearview mirror can not only determine the distance from the vehicle behind, but also observe the vehicle behind when turning. In addition, it can effectively prevent rear end collisions and avoid scratches. For vehicles following closely behind your car, due to the presence of blind spots, the left and right rearview mirrors cannot be seen, and can only be seen through the inside rearview mirror.
