Head on out to Green Bank, WV, and you're likely to notice what looks like a giant satellite dish on the horizon. Only it's not a satellite dish. It's actually a fully steerable radio telescope – the largest of its kind in the world. It's funded by the federal government through the US National Science Foundation and operated by National Radio Astronomy Observatory. In short, it's one of the most advanced telecommunications devices in the world. So you'd expect them to service it with suitably advanced vehicles, right?
Wrong. Radio telescopes are hyper-sensitive to interference. That's why this one is located (alongside the NSA installation at Sugar Grove) inside the United States National Radio Quiet Zone. It's also why the NRAO only uses old diesel trucks to get anywhere near the telescope. Some of those trucks are 45 years old, but because they don't use spark plugs, computerized ECUs or even door chimes, they don't mess with the telescope.
