I cycle commute. The story is normal cycle activity. Do cyclists
dressed in $400 of Puerto Rican halloween costume say "passing on the
left'? no way. If asked politely " you stupid SOB, say passing on the
left" are they offended? off course.
they snarl: "you gotta mirror stupid you blind"?
The problem can be interpreted as the Mulesanne effect: besides
passing is fun, and you are the only person the PR passed all day
after getting blown away by a granny on a trike, passing at high speed
differentials is loads of fun. manly.
"he'll see us" you bet.
