I know the question sounds pretty stupid, but their are people that just leave it in D and push the accelerator.
There are others who put it in 1 to take off then continue to shift to 2 then to D3 until they reach D4 for a desirable speed.
(Is their a precise moment to shift into 2 then to D3 and so on?)
And their are some people who hear the engine for a precise moment to pump the accelerator to get to a faster speed.
(Is their a precise moment to push down on the accelerator?or do you just have to hear it and feel it?)
