You know, I read this whole back and forth, and the only takeaway I have is that you have absolutely no idea how any of these technologies work. Like at all. I’m not saying this to be a dick or anything -it’s ok to not know things- but it’s painfully obvious in this case because your lack of fundamental understanding is the core of your argument.
And if you did understand how the tech works, you’d probably get why those options are used instead of your layman’s idea of a good idea. Which is not, in fact, a good idea at all for a variety of reasons. Which is exactly why these other things are being discussed and supported by people who do understand them (and I’m not talking about the rest of the Lemmy comments either, I mean in the real world).
There are tons of scenarios where cell towers/fm transmitters for an area would go down, but cars would still be fully operable. But even if that wasn’t the case, why do you want to remove a public safety option that currently exists, even if you don’t and won’t use it? The only people who benefit are big companies (the exact ones whining they don’t want to comply) that don’t care about you, so why do you give a shit if this inconveniences them?
