What are the reasons for frequent stalling during the hill start in Subject 2?

[MacColin]

The reasons for frequent stalling during the hill start in Subject 2 are as follows: 1. The tightness of the vehicle's clutch varies from one car to another. The amount of clutch release needed to reach the semi-engaged state differs. 2. Releasing the clutch too quickly. Remember to release the clutch slowly, as the semi-engaged state is usually in a middle-to-rear position. Releasing it too quickly might cause a timeout. 3. Releasing the brake too quickly. Once the semi-engaged state is found and the vehicle is shaking significantly, releasing the brake too quickly can cause stalling because the power hasn't caught up yet. In this case, the foot brake should be released gradually.
