A radio station in Seattle, KUOW 94.9, crashed and permanently bricked the entertainment system in Mazda cars after the station broadcasted images over the air that lacked a filename extension. https://t.co/8npKfgYTXT— Chad Loder (@chadloder) February 9, 2022
a couple things: there's difficulty of blasting a big enough signal without the FCC finding you. maybe you could do it at close range if you were near a vulnerable vehicle that had the radio on. oh also it's a proprietary standard that requires a number of components to implement, none of which are open source or for sale to an enthusiast. if you somehow did manage to get the necessary tech and build a short range implementation, your only reward is breaking an expensive but non-critical component of certain vehicles, with no direct potential benefit to yourself.
Most proprietary things aren't particularly hard to reverse engineering if you have the time and equipment. The basic equipment you would need costs tens of thousands of dollars though. Like, all added up together, not individually. Microscopes, signal generators, oscilloscopes, random things from digikey you would order as you figure out you will need them, basic workshop stuff, probes, it all adds up.

Thank you for your service. I was wondering if it was proprietary and controlled these days.
