Man, my home state has really taken a turn. Its always been tolerant (in a "you do your thing and leave me the fuck alone" way) but never ultra-liberal/big government.
It surprised me as well. But then again, Oregon won't even let you pump your own gas.
I don't like this proposal at all on privacy grounds, but I'm on the fence about whether the basic idea is fairer than gas tax. Gas tax would ideally be good enough because heavier vehicles get poorer mileage and so pay more tax per mile. But as mileage improves for SUVs but not so much for cars, the gap gets closer. Then there's the sportbike that causes almost no damage at all, but gets similar mileage to a Corolla.
I'm thinking that gas tax is still a good enough approximation, especially once you add in the cost of the GPS units and their maintenance.
