the worst part about passing someone up is when you get stopped at the next light and they speed right past you because they didnt have to slow down. thats when I feel like an a$$hole.

"Tag, you're it" as you pass them seem to work on occasion. The one time I said on your left, the guy turned left.

it's really not that complicated folks. you should always announce that you are passing by saying "on your left" or "passing on your left" but you shouldn't assume that the person you are passing is going to automatically respond in the appropriate way. chances are none of you are working to maintain a consistant cadance or heart rate, so slowing down for just a second to give the person you are passing time to figure it out and give yourself time to see how they react isn't a big deal. show a little patience, don't be like those jerks on TT and tri bikes who refuse to slow down and race down paths and streets like they're on a close race course.

Most dual-use trails around here have a 15mph speed limit anyway.

I just start laughing out loud. People give me a lot of space. If there are two people...one often grabs the arm of the other and pulls them safely off the path.

I almost never call out. Even then only to peds. Bikers, I wait until traffic allows me to go nice and wide around them. BTW I usually just click my foot in and out of my SPDs. Sometimes peds are surprised enough to look back to see what's up.

i really only use it when i need to pass a pedestrian. but i agree it always makes me feel like an ******* when i'm yelling at people... if i can manage to get around them without saying anything i generally will

On my canti equipped touring/ CX-y trail bike I just chirp my brakes from about 20m away.

i was on a path once and a woman was riding slowly down the middle. I came up behind her, whistled (not like a two fingered cab hailing whistle but rather like a quick singsongy one) to alert her that i was there and then passed on her left (mind you not much faster till i cleared her and i had already slowed before getting to her). She proceeded to yell at me for not saying "on your left." I would have thought that someone who is that caught up in bike path etiquette would be riding on the right side such that on her left is the only place to go as opposed to rolling down the middle of the path at 5 mph giving sassy lectures to everyone that doesn't adhere to what is apparently an individualized version of the code.

Shoulda shown her a little U-Lock etiquette.
