To clarify, aren't these standards mostly relevant where heavy bicycle traffic exists? Do they still apply in areas with little to no bicycle traffic? I'm assuming you're mostly referring to this famous manual: https://en.wikipedia.org/wiki/CROW_Design_Manual_for_Bicycle...
There is no bicycle traffic because there are no bicycle roads. It's incorrect to claim that we shouldn't build bicycle roads because there's no bicycle traffic :)
