In my opinion and by experience here in the states the etiquette kind'a sucks big time. Don't know what else to tell you. Here the weather is pretty nice and a bunch of suckers with mirrors, bells and who knows what else moving around saying at your left, right above and below. Freds everywhere. rather see a poseur than a fred due to the fact that the poseur probably wont get mad even if you are riding at is wheel or if you dont say a sh...T when you are passing them.
TOday i heard a sucker saying i dont want you near me... i went like W..T..F?? THen i asked him twice what he said and he changed the phrase to something else maybe because he thought i was going to hit him in the face or something. Poseur is way more tolerable than a fred in my opinion.
Nice bike my friend.
