I find it rather silly that people object to paying a tax to support bike infrastructure (a whopping $15 every umpteen years that they own the bike) on the grounds of virtue. "Healthy happy lifestyle", "not contributing to global warming", "saving wear on the roads", etc. are all versions of "look at how good I am, compared to other people, why should I have to pay a tax?".  One letter actually says the tax is a "resentment tax aimed at punishing bikers for using a non-polluting, asphalt-sparing, clean-energy alternative to driving a car and for our feeling pretty good about that."  And then there's the claim of a "healthy transportation option" as opposed to others, clearly considered unhealthy.
