But the thing is, don't necessarily presume they didn't see you! I had an encounter with a particularly cantankerous elder* "gentleman" this past summer.
Long story short, this involved a right hook on a main street in a residential section of our city. I was able to avoid the hook, by turning right too. What was most interesting was what happened next...I was then riding along side him, shaking my head, and he rolls down passenger window and launches into a profanity laced diatribe, while trying to nudge me off the road into passing yards. This was then followed by his admission that he saw me on the main road and fully expected me to stop and yield to him, because: "...you have no business on the road, after all a bicycle is a toy, right?..."
That thought crossed my mind too.
