Oh my God man. I mean it's annoying enough that sirens are annoyingly loud. They don't just get my attention, they piss me off too.
After living on a major intersection in St. Catharines I honestly don't understand why the fuck emergency vehicles need such obnoxiously loud sirens. I don't believe there are blind people driving, and if they are well you have bigger problems than simply trying to get past them. Seriosuly, a chime or a chirp would do instead of a ridiculously loud HONK or WOOOoo.
