I think there is a different connotation to "slow is smooth, smooth is fast", but agree it isn't really a great analogy for production, because it is about learning.

What they mean is that you can't be fast (on a track) without being smooth, and that typically beginner-to-intermediate drivers/riders are trying to be fast in ways that make them less smooth, and ultimately (and counter-intuitively) makes them slower. So the advice is to forget about being fast and concentrate on being smooth. The speed will come.

I do think this has value as an analogy for software, but it is in concentrating on your tooling and methodology - smoother operating will deliver real value faster than just trying to type fast.
