Players need to control the speed of the racing car so that it can accurately stop at the designated parking position, which is usually indicated by a red line or a green area as the parking target. For example, in "Extreme Car Parking", there is a speed control slider for the racing car on the left side of the screen. After the player drags the slider with a finger to set the speed, the racing car will start running at the set speed and slide automatically until it stops. 19
