This isn't about courteousness, it's about complaining about uncourteousness...
Sorry, I was not aware you were clairvoyant, and knew what this thread is all about. I just started the thread, what do I know?
But let me ask you a hypothetical. You're walking alone on a popular bike trail, nine feet wide. Bikes are passing you at the rate of about one every 2-3 minutes.
Do you:
1) Take notice and walk over on the right side of the trail so the bikes can pass; or
2) Walk down the middle of the trail and act surprised when a bike comes up behind you.
I am always courteous.
And the 'this' in my post is reply to the quote you put up about... cyclist want it both ways.
