A comment from a poster called La Hondan captured our current state of affairs perfectly and the comment goes well beyond the bicycle versus auto issue.
From La Hondan -
"I think this is an symptom of a deeper community problem. This is not about bicyclists, motorcyclists, car drivers, horseback riders or pedestrians. It's about courtesy and civility. I see more and more selfish, "me first" behavior on our roads all of the time. Whether it is a clump of cyclists blowing through a stop sign, or a tourist poking up Hwy. 84 at 15 miles below the speed limit but never turning out to let traffic flow, or cars or motorcycles recklessly passing on blind curves, it is all about "Me! Me! Me!" and everyone else be damned.
Is it the overwhelming sense of privilege that seems to inhabit the minds of so many of our neighbors? Is it just bad manners and selfishness? Is it petty-mindedness and shallow thinking? We're supposed to be a community, let's act like one."
Kudos - perfectly stated.
