I think they should charge each vehicle a fee, say $25 or so, when the studs are installed to pay for the damage they will do. If you live on a hill with some elevation black ice can be a problem on many mornings even in Seattle or Potland, so studs are the way to go.
And a $1000 fee for each truck because they have to replace the highway surface on the passes each year.
Oh wait, there is already a fee........
It's called Federal and State "Fuel tax" and it is all supposed to go to road maint but they spend it on beautification corridors and meetings in Hawaii!
