What are the techniques for smooth clutch and throttle coordination without jerking?

[LaAdam]

When starting: You need to press the clutch and brake pedals all the way down, then slowly release the clutch. When shifting gears: Release the brake, press the clutch all the way down, and after completing the gear shift, lift the clutch at a steady speed (except for first gear). When decelerating or braking: Press both the clutch and brake pedals together until the vehicle gradually comes to a stop. Then shift to neutral, engage the handbrake, and release both the clutch and brake simultaneously. The clutch states are as follows: Free travel: When you initially press the clutch, there is a small play in the clutch pedal, known as the linkage state. During this time, the power between the engine and the transmission is not disconnected, so no operations other than pressing the accelerator can be performed. Semi-engagement: When the clutch is pressed down a certain distance, it enters a semi-engaged state, meaning only about half of the engine's power is transmitted to the transmission. The semi-engaged state is primarily used when starting, and it is also the reason many beginners often stall when first driving a manual transmission car.
