There has got to be some value in what bicycles DON"T require of the transportation structure. The numbers and usage are so disproportionate: a commenter in the link above figured a fair share to be 85¢. Most of us drive, too, and pay our fees and choose to use the road in a less traumatic manner. I'm really tired of the double talk from the city advocating increased bike use and doing substantially nothing to really encourage it. Even the mention of a fee is a step backwards. Better be charging the skateboarders in the bike lanes and the runners and walkers on the multi-use paths something, too. We already pay....and require less. We shouldn't acquiesce to any consequence car-headed government wants to lay on us for our commitment to bicycling.
