700-800 cyclists are killed each year in the U.S. while bike riding. Countless others are seriously injured while bike riding. Trying to reduce those numbers is, ultimately, what the concept know as VC is about, particularly with respect to the fact that probably more than half were violating
Basic VC rules (riding on the wrong side of the road, swerving in front of traffic without yielding, riding at night without lights, entering intersections from sidewalks at relative-to-peds high speeds without yielding, etc.), and most of the other half was not engaged in
Advanced VC best practices (riding further left to be visible, predictable and with improved sight lines and safety buffer zones rather than too close to the right, particularly at ALL intersection approaches, going straight at intersections and any place where there is a potential conflict with right turning or right tending traffic without looking back, etc.).
With respect to why the concept needs a label, it's not much different from why Prince's attempt to shed his label (name) was not very effective.
If a concept has value, and I believe this one does, then it's very helpful to be able to refer to it by name. That's all.
What you refer to above as "VC zealots" sounds like "
Strict VC zealots". I don't know of any of those. Do you?
EDIT: For definitions for what I mean by "
Advanced VC", "
Basic VC" and "
Strict VC", please see the
OP of the
Some VC definitions thread.
