One can hear an ambulance in the next block
OK. So, suppose you and I are riding along when you hear the sound of an ambulence, somewhere, but I am a deaf person. What is it that you do that makes you safer, at that point, than I am?
This is the presumption that I don't get. Quite understandable that people *like* to hear far-off ambulences, or even nearby motorbikes. But when it comes down to it, what do you *do* about the ambulence that makes you safer, if you can't actually see it?
If others feel safe with anything from a single open backed earpiece to full on sealed ANR headphones that's fair enough. But don't label me a poor cyclist because I'd prefer not to.
How these things turn around. I don't think anyone is making the argument that riding without headphones is unsafe (!!), only that if you are observing correctly, it is not necessary to be able to hear (notwithstanding that significant noise can be heard over music anyway).
If you look up the thread there are no shortage of comments that if you ride with headphones in, bad things are bound to happen.
