When driving, the ideal way to apply pressure onto pedals is by pressing gradually as when you press the pedal more fuel goes into the engine and the speed of the car increases. Because of that, when you are driving it is better to have a steady increase in the pressure because that allows you to maintain the control of the car and avoid risky situations.
