Where I live bikes are a viable everyday transportation mode - particularly in combination with public transit options. All situational anecdotes and regional policy vagaries aside - the critical issue underlying this discussion (both the off topic message board debate and the original topic); is that automobiles can no longer be consider the default, primary and most-rightful road users.
Am confused about your antipathy towards bike lanes - would you rather that cyclists occupy the lane? The biker in your story sounds like they would have been safer doing that. (the disappearing lane thing is terrible and sounds like a half-baked design FWIW).
The idea that the roads are mainly for cars is destructive to communities social and physical infrastructure, the global environment, individualās health; and this is thankfully changing. I am happy to see more cyclists on the road, it increases awareness and safety among drivers. As a driver it can be frustrating to encounter a slower moving vehicle, and as a cyclist I try to avoid biking on thoroughfares (because of people driving like you describe). There has to be a new type of coordination that allows both modes to coexist.
