OP’s instructions are incomplete and will lead to a stall, especially if car is uphill.
You are right in that most cars need to be given gas between half clutch and full clutch or it will stall. There are some vans and trucks where the engines have enough torque to allow you to dive from half clutch to full clutch without ever giving it gas. But again that would never work uphill.
Oh god. The mother has 5 fingers.
5 fingers, not including thumbs…
