Why does the car roll backward when starting on flat ground?

[DiTucker]

All manual transmission cars may experience rolling issues if the coordination between the clutch semi-engagement and the brake is not properly managed, which is a matter of driving technique. Rolling backward indicates that the torque transmitted from the engine to the wheels is insufficient. Below is additional information on car rolling backward: 1. Car rolling backward: Refers to the distance the vehicle moves backward when starting. During the driving test, it is stipulated that if the vehicle rolls backward more than 30cm when starting, it will be judged as a failure. 2. Precautions: (1) The throttle must be pressed gently, and the clutch should not be released at this time. (2) Once the throttle is well controlled, release the clutch and then the handbrake. 3. Parking: After parking, it is advisable to shift to neutral, pull the handbrake tightly, and then turn off the engine. Be cautious not to use a high-pressure water gun to wash under the hood in cold weather to prevent water accumulation in the gear mechanism from freezing. Pay attention to the parking position to avoid being bumped, squeezed, or pushed by others when parking, or getting stuck on a steep slope due to the vehicle rolling and locking the mechanism.
