I want to know the answer to the following question:
What is the Swiss private-public managed road network funded by?
All the background I'm provided with is that "The Swiss autobahn/autoroute system requires the purchase of a vignette (toll sticker)—which costs 40 Swiss francs—for one calendar year in order to use its roadways, for both passenger cars and trucks.". Is that enough to answer the question?
Answer: no
