Traffic situation: Facing traffic congestion, a red Mazda CX-8 brakes to a stop. About two seconds later, the driver releases the brake (brake lights go off), and the car rolls backward, impacting the front of the vehicle equipped with a dashcam.

Driving skills: Many drivers habitually relax their feet during traffic jams by shifting to neutral and releasing the brake. However, on uneven roads, even a slight incline can cause the car to roll backward when in neutral. Without careful observation and sufficient driving experience, drivers may not realize their vehicle is moving.

When stopping at a red light or due to traffic, drivers should never release the brake unless the vehicle has an auto hold feature. Even with auto hold engaged, drivers should remain attentive to their car's movement and be ready to intervene if it begins to roll, as seen in the video.
