What Causes the Car to Roll Back in Subject 2?

[FelicityAnn]

Subject 2 rollback can be caused by either rolling backward or stalling. Below are detailed explanations of the causes and solutions: Rolling backward: When parking on a slope, even if the handbrake is pulled, the car may roll backward once the foot brake is released, which is due to the handbrake not being pulled tightly enough. The solution is to prevent the car from rolling backward. When starting the car, slowly lift the clutch with your left foot. When the car hood noticeably vibrates, gradually release the brake with your right foot. Once the brake is fully released, slightly lift the clutch a bit more with your left foot and hold it steady. Then, release the handbrake with your right hand, and the car will start moving forward. Stalling: When starting the car on a slope, if the left foot lifts the clutch too quickly, the car will stall. Lifting the clutch too quickly is the root cause of engine stalling. The solution is to prevent the car from stalling. When starting the car, the left foot must slowly lift the clutch and pause at the semi-engaged position. Once the clutch reaches the semi-engaged position, keep it steady, then gradually release the brake with your right foot.
