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…
You don’t need to put it in the gear opposite to the direction it’ll roll. Generally you want to put it in the gear with the lowest ratio (which in my car I think is first), as that will require the most amount of force to turn the engine. But also some engines shouldn’t be rotated backwards because that might damage them. So that would mean put it in first facing downhill or reverse facing uphill.
