This technique allows the driver to have a direct line of sight to what is behind the vehicle, increasing awareness of the surrounding environment, including pedestrians, other vehicles, and obstacles.

Relying solely on mirrors can lead to potential hazards being overlooked.

Thus, turning your head to look through the rear window empowers the driver to maintain better control and safety when reversing.
