I derived a formula for myself: “Roads are the embodiment of the state, and cars are the embodiment of citizens.”
If both roads and cars are bad in the country, then, most likely, this is a poor state with a small budget and poor people.
If the roads are good, and the cars are bad, then this is most likely a totalitarian state where power is strong, and citizens do not have the freedom of entrepreneurship.
If the roads are bad and the cars are good, then, most likely, it is a young developing state that has embarked on the path of capitalism, but has not yet got rid of corruption.
If both roads and cars in a country of high quality, it is in most cases a highly developed, rich country with a market economy and free citizens.
