I am not aware of anyone else making this exact analogy. It is possible other people influenced this train of thought, though. I think I was just trying to explore how media portrays firearms gratuitously and unrealistically, and then trying to find another common machine that is portrayed as unrealistically in film.

Now that you mention it, there has been a story circulating for a few years in response to "We need to regulate gun owners like drivers" followed by an explanation of how silly that comparison is, but I don't think I had that in mind when writing this.
