Or just hold the brake, put in gear, then release the brake, rev up the engine to 3k rpm and release the clutch. Not as good for the motor and gearbox but faster lol

Edit: Ya’ll, if one knows what they do, and knows the car, speeding the motor up to a specific amount, often 2-2.5k rpm, and releasing the clutch a specific amount, takes less time than gravity needs to overcome the inertia. I’m almost always literally starting while practically still standing, because it takes ~0.1 second to do said things, if you know the car and its sweet spots.
