Eventually the roads will need to be paid for. Will be fun when the owners get their bill.
The Europeans pay for their roads differently than the USA they charge a vignette when you enter the country good for class one and two roads it’s mandatory. All motorways are tollways so are most bridges and tunnels.

Nearly every EU nation has it’s own vignette that you must buy once you enter with a vehicle from another nation. There is a growing number of EU nations going to pay by the miles for class one and two roads not just tolled motorways.
The high VAT taxes and petrol.taxes are not used for motorways those go to social programs.
