I’m practicing for my driving licence and I’m going to driving school, just out of curiosity though I’ve looking on YouTube how to start and run a car and I’ve seen at least 3 different methods, I dunno which one is the correct. Things like the order when you release a pedal or when you need to press the clutch keep switching…
It’s been a few years for me but the last manual I had would stall if you didn’t give it a little gas before the clutch was fully released. Maybe I wasn’t holding it in that sweet spot you mentioned long enough, before letting the clutch go completely?
There are cars where you might need to add gas, and ones where you don’t. The above definitely worked in the car I learned to drive in.
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.
