One of the Startup Weekend ideas I keep playing with is a Bluetooth jammer that can selectively stop these public nuisances. I know it's illegal, but so was Uber when it started. And yes, being able to block people's headphones and other stuff would be bad, but I'm moving towards that being acceptable collateral damage. Fed up of rude idiots playing really bad music at massive volume (and why is it that only people with appalling musical taste enjoy blasting it?).
