The method that is NOT part of controlled braking is flicking the steering wheel rapidly. Controlled braking is a technique used to maintain steering control and deceleration without losing traction. It focuses on smooth application of brakes and controlled steering to avoid skidding or losing control of the vehicle.

In controlled braking, applying brakes as hard as possible without locking the wheels allows the driver to slow down effectively while maintaining vehicle control. Keeping steering movements small helps ensure that the vehicle remains stable during braking, reducing the risk of losing traction. Stab braking, which involves applying the brakes until just before the wheels lock, is also a recognized technique to help regain control if skidding starts to occur.

In contrast, flicking the steering wheel rapidly can destabilize the vehicle and lead to loss of control, especially while braking. This action could increase the risk of skidding or flipping, and does not contribute to the controlled deceleration needed in emergency situations. Therefore, it stands out as the method not included in controlled braking strategies.
