Rearview systems are safety features in vehicles designed to assist drivers in reversing and parking. These systems typically include a camera mounted at the rear of the vehicle, which provides a live video feed to a display inside the car. This helps drivers see obstacles, pedestrians, or other vehicles that may be behind them, reducing the risk of accidents. Many modern vehicles also incorporate sensors that detect objects in the vicinity while reversing. These sensors can emit audible alerts or visual warnings on the display, further enhancing safety. Overall, rearview systems contribute to safer driving by improving visibility and awareness during maneuvers.
