I think there's too much involved in getting a whistle to your mouth, at precisely the time you need to be covering your brakes and being on high alert for someone to jump out in front of you.

I have a rather loud squeeze horn on my commuter, but I'm seriously considering one of these. I don't have any compunction about being loud when people are oblivious. I would give them the benefit of the doubt and holler, or use a bell, though, before blasting them with an air horn.

SK, I so rarely get a response to my bell even on our quiet, generally non-congested MUP, that I hardly bother with it. At least there's a chance they'll hear me holler.
