You know what else is stupid loud and annoying? Ambulances. Fire trucks. Diesel buses. Electric ones arent great either if they have those wire systems overhead, those hanging systems make lotta noise too. Sometimes they're separate but they have to make an obnoxiously loud whirring sound while accelerating anyway. Large trucks used for hauling stuff. (Ever notice how loud a ups truck is?) Buses with air suspension that raise and lower and beep all the time with stupidly loud systems (PSSSSST!!! BEEP BEEP BEEP BEEEP BEEP WWHOOOOOOOSH BEEP BEEP BEEP!!!!).

I've lived in enough metro areas to know loud bikes are low on the list. There's plenty more annoyances. God forbid you live near an airport, hotel (idling diesel buses), or a plethora of other annoyances.
