Bluetooth speakers should have a community override feature
I ride the train a lot and I often encounter rude people blasting (usually bad) music from a Bluetooth speaker. It happened again just yesterday, with a guy who also had a massive dog that he didn't seem to be in control of. The typical advice is to *not* confront these people, because they're hoping to start a fight. But I really wish there was a way I could shut down that speaker.
Maybe Bluetooth speakers could have a community override feature, where if enough individual devices try to connect to it, it will relent and let someone else takeover. Basically, if you piss off enough people (like, say, a train car) then you have to pass the (digital) aux cord.
Obviously, you shouldn't do this for other Bluetooth devices, for security reasons. But speakers are kinda unique in that they don't have many security implications, and when used incorrectly they piss off almost everyone equally. I know manufacturers won't build this willingly, but I wish they would.
