A system, vehicle, method and non-transitory computer readable storage medium for improving driving safety are provided. The system includes: a steering wheel; a paddle attached to the steering wheel; a pressure sensor, which is installed between the paddle and a contact point of the paddle to the steering wheel and is coupled to a control component, wherein the pressure sensor is configured to sense a pressure exerted on the pressure sensor by the paddle and send the sensed pressure to the control component; and the control component, which is configured to, in responsive to receiving the sensed pressure, determine a level of deceleration corresponding to the sensed pressure and send a deceleration command which instructs to decelerate, based on the determined level of deceleration, a vehicle on which the system for improving the driving safety is installed.
