"Are roads really payed from gas taxes? Everywhere?"

Fuel taxes are quite common. In some areas they do make up a large component of the road funding. Finding a replacement for them is a major issue.

"Somehow even relatively poor countries manage to have good roads. We will save elsewhere. Most of the taxes go into the social bucket in most countries (retirement, social security, health, education) anyway."

This doesn't make any sense and lacks factual support. How do the poor countries pay for the roads, and which counties are these? What are we saving and where? The majority of current taxes going to social programs has no relevance to this discussion. If we're eliminating a current tax and having the same service costs (or more due to increased weight), a new one will need to take it's place.
