Uh, maybe look at the preceding sentence?
"...a radio station in the Seattle area sent image files with no extension
Now that is impressive software coding when something as simple as an image file without an extension wipes out most of your electronics.
Western Washingtonians' heads would have exploded if the radios were stuck on the "Joe Rogan Experience." Then Mazda would have to pay the Sunshine Cleaning Company for a lot of car interior jobs.
I had an acquaintance who was a software architect for a major (Japanese) auto company. Their entire SW development process consisted of writing specs which were shipped to "code farms" (I believe he said in the Phillipines) where low-paid contract coders implemented them. (Not a line of code was written in the US.) In that kind of environment, at best you get exactly what the spec asks for. If it doesn't say anything about robustly handling image files without extensions, you won't get that.
