In which case the question gets inverted:

Why of all common things you could CT scan and show people, you choose something that is kinda obvious to anyone who has thought about it for five seconds? I don't think average people struggle to understand the concept of "electricity makes wire hot", especially if they lived at the same time as normal car cigarette lighter usage.

Lumafield posts tons of these. I don't think the average person has thought at all about how these work, and even if they do, the appeal of these is to look at the pretty pictures (and demonstrate the analysis that is possible non-destructively to their target audience), not to understand "electricity makes wire hot".

They have a scan of a dang football, and it isn't because people don't know there's air inside: https://www.lumafield.com/article/ct-big-game-football

Those who have thought about it for more than five seconds understand that there is more going on inside of a normal car cigarette lighter than "electricity makes wires hot."
