>At some other countries (e.g. Portugal, Italy, France), they have tolls for the highways so only the cars crossing that road pay for the cost.
JFYI in Italy you pay BOTH a "fixed tax" (which is function of the horsepower of the car engine) AND most highways have tolls.
You pay with the fixed tax the "general maintenance and development" of ALL roads (excluded toll highways) and you pay the toll on a per use basis, as highways are largely "private" (technically they are public but object of concession/grant to privates).
Thanks for the detail about the road taxes in Italy. I had to stop so often on the road headed towards Milan to pay tolls every couple of kilometres and you still have to pay an yearly cost as resident, great.
Normally on highways in Italy you take a ticket when enterng the highway and pay when you exit, the toll boxes every few kilometres is something that was removed everywhere in the 70's (though I cannot exclude that a specific road somewhere in Italy still has them).
