I appreciate the way you framed your response. If you haven't noticed, that doesn't tend to happen a lot on this website Both of the times this week this happened to me were classic examples of your point.

I think another contributing factor is that so many cyclists riding are adults picking up a skill they learned as kids but really without any rules or expectations of how to operate a bicycle in traffic, so they're now teaching themselves as they go. I'm sure the LAB courses have their graduates, but few of us rode responsibly and in a completely legal manner as kids, so now as adults that's our primary template, with automobile driver's training as an overlay of what we're supposed to do as cycle commuters. It's no wonder that there's a fractured view of how cyclists ride in traffic.

In a utopian model, we'd have a concerted effort to encourage/incentivize adults to take some sort of skills class and have kids do the same. Eventually, drivers then would have a better idea of what it's like on the outside of the cage in traffic.
