It seems there are a couple of states floating bicycle registration requirements to “allow” us to share the road with cars.  Oregon’s KBND reported the  Bicycle Transportation Alliance is opposed to a mandatory $26/year bicycle registration, stating that opponents claim other states have failed to develop successful programs.  This program’s claimed goal is to get cyclists to share in the cost of developing roadways and systems to accommodate bikes.
More in depth is The Examiner’s 2-part series on why NYC’s consideration is unfair and unlikely to encourage bike usage.  They pick apart the points raised by Ben Myrick in Seattle, who is advocating for bicycle licensing and related laws.
Why the sudden interest in this?  Well, it’s a double edged sword…there are more people commuting and riding bicycles (good), which means more opportunities for, ahem, interactions between drivers and cyclists.  What’s the word in your community?  Any talk of this?
