This seems so nuts and so sad in so many ways, and I am shocked that such progressive states that are so bike friendly are on the front lines of it! Before we even consider any of the other reasons it is crazy, it just does not at all fit in with the American (or any other country I can think of) tax policy. When you buy a bike or a car (or a used car), you pay sales tax. SALES tax. You do not pay any usage tax because you bought a car. Highways, bikeways, etc are public goods. Certain bridges, tunnels, and autoroutes have tolls for usage, although the tolls only pay for a fraction of their general construction and maintenance. I totally support the idea of tolls, and would be ok with tolls on super fancy awesome designated and special bike infrastructure (that parallels super fancy/special autoroutes or whatever), but charging bike owners a special tax is just totally nuts! Not to mention that it seriously distorts incentives, and that there are extremely valuable positive externalities created by people biking (and not driving or otherwise congesting roads), so if anything you should give bike owners a discount on taxes for biking. Now living on the East Coast where the weather wreaks havoc on the infrastructure (you can't actually imagine out there in CA, I feel like the worst most potholed roads out there are maybe the baseline/mildest ones here), I find this even more shocking. Me on my 18 pound road bike is the least of the wear and tear on these roads. I thought OR was supposed to be so bike friendly and progressive- not only is this shocking, but I can't believe the people of OR put up with it! (I don't know details about the tax, but just a gut reaction, sorry for the rant, I know I am preaching to the converted...). I hoep there is some sort of justification for this that I am missing. Gotta study.
