The car analogy is just right, IMO. It's a functional description of how a car works at a high level, so that we can understand how it's put together; and if we're reasonably expert in mechanics, we can fill in a lot of missing details. Whereas "a box that you sit in that lets you get to where you want to go quickly" leaves out far too much detail.

Too many descriptions of tools for devs sell benefits instead of functions. This is normally good sales practice, but devs are experts in the mechanisms behind the tools they use, and they generally prefer more functional descriptions so that they can more quickly evaluate whether any given tool is a good fit for them, and what its strengths and weaknesses will be.
