Rationality isn’t particularly common among Muggles. Like, at all. I was thinking more about the physical tools, anyway—there’s nothing stopping a wizard from using Muggle tech as long as they don’t have lots of magic going on nearby (or I would have expected some Muggle-born child to complain offhand about how they can never make the TV work over summer holidays and their parents are annoyed about all the brownouts). Whereas Muggles cannot use wizarding tools one bit—or even see wizarding locations.
