Here's a slightly different take. Bicycle tax is mentioned as only one of several possible fees.
This appeared in the 10/27/08 issue Eugene Oregon Register-Guard. (I had to cut and past, there was no direct link.) Our roads, btw, are in really rough shape.

Tax all users of the roadways


I read in The Register-Guard recently that there is a measure to fund street repair with property taxes — $35.9 million over five years.
Are only property owners allowed to vote on this issue? It doesn’t seem quite fair to allow someone who won’t have to be ponying up to say someone else must pay.
Why not allay these costs with, say, bicycle and car taxes? What about the trucks that are responsible for a great deal of the damage?
How about the visitors to Eugene? Shouldn’t they bear some of the cost?
Property taxes are high enough! I think Eugene ought to ease off a bit on penalizing folks who’ve chosen to buy their homes there.
Tax all the users of the roads, not just the home owners.
