 This road is headed north into Canada, just east of the Great Glacier Waterton Lakes International Peace Park that straddles the Canada-Alberta border. The road has been built, and then you'll see that the road has been maintained, and in many countries roads are built and maintained with small taxes on gasoline, petrol, and motor fuel. When Economist policy makers talk about using taxes to reduce fossil fuel use. That would assume that the money raised is not used for purposes such as building and maintaining roads that actually serve to promote more use of fossil fuels. It is quite possible that the sort of tax that is used to fix the roads is actually a sort of subsidy for fossil fuel use because it encouraged more use, and if you want to use a tax to reduce fossil fuel use, the money has to go to something other than promoting more fossil fuels.
