Or think of it in the same way as a musician plays an instrument - watch a professional guitarist/saxophonist/pianist's fingers when they're playing - there's a hell of a lot of action going on there and it doesn't necessarily seem smooth (in a "fluid" sense at least)... Now close your eyes and listen - it sounds smooooooooooth... So each individual action of the fingers (and embouchure, if it's a wind or brass instrument) is conducted in a positive, predicted, and predictable, manner. Just like inputs to the throttle, brakes, position on the bike etc. Put it all together properly and the combined result is smooth.
And, like playing an instrument, it's much easier talking about it than doing it....
