Why is quick, sudden braking considered as an effective collision avoidance method?

Quick, sudden braking is particularly effective as a collision avoidance method because it enables drivers to rapidly reduce their speed or come to a complete stop in response to an unexpected obstacle or hazard. This immediate change in speed can prevent or mitigate the severity of a collision by increasing the distance between the vehicle and the object that poses a threat, effectively allowing for adjustment to the driver's path in a critical situation.

Braking effectively helps to close the gap between the point of potential impact and the actual vehicle position, giving the driver a chance to either avoid the obstacle altogether or lessen the impact severity. This mechanism of rapid deceleration is crucial in emergency scenarios where time is of the essence, and quick reflexive actions can significantly impact the outcome of an impending collision.
