Ok, I'm mostly just whining, but studded tires are what make Oregon roads kind of sucky. Folks get their tires switched over to studs in mid-fall and ruin the roads from then 'till mid spring, rarely, if ever having need of them (and the rest of us just pull out the chains for the occasional icy or snowy day or trip over the mountains). I often drive as close as I safely can to the center line or almost on the shoulder to try to stay out of the ruts the studded tires make. ...Though the log trucks probably have a big impact too.
That said, it does make sense that all users of roads should be responsible in some way for their upkeep, commensurate with how much those roads are used. How to do this without unfairly taxing those who do long-distance out-of-state travel would be tricky. Its absurd to say that this unfairly targets owners of efficient vehicles. Everyone gets charged the same tax per mile, efficient-vehicle-owners still pay less for gas.
