Can't say what they use the money for exactly, but fuel taxes in Europe are VERY high, on the order of $3 per gallon or more. The general high quality of most road systems in Europe would lead me to believe that a fair chunk of that is spent on the roads themselves, not on healthcare costs.
參考: 10 years of living in Europe. And paying through the nose for gasoline over there.
