Which is one of the most unappealing thing about the marketing material for LLMs services like Copilot. The issue was never the speed of writing code, more often than not, you're contemplating if you should write it. And if you need to, how much of it should you write and how to make the eventual rewrite easy.

If you're experienced enough, you either knew the rough way to code a task or realize that you need to take time to investigate the problem space. I don't think I ever ask myself what should I do to write more code with less effort. All the improvements I've made was to target precisely the thing I wanted to edit.
