its why we have laws
Yes, unfortunately society has to have laws to protect some citizens from themselves and the majority from those citizens, either due to ignorance our simply selfishness. Generally we don't need laws for most things, "there is no specific law regarding dont ride your bike backwards while blindfolded", and its only apparently common things that have to be put into law that some people just try and get away with. It should be obvious to most people that starting up your lawn mower at 3 am is not the right thing to do, but no, municipalities have to have bylaws stating what hours these devices are permitted between, because some either dont care about their neighbours or are simply ignorant that noise may effect others..
Same goes for driving with headphones in my country, its illegal whether car, bus or bike......its different to having a speaker, as the headphones can block external noise, but then again, that is why we have a law, because some are just ignorant and or selfish of the situation.
