I agree that there's advantages to the user pay system. People are enthusiastic to use a new bridge, less so when they find out that they have to pay a toll to drive over it. Various charges can be used to manage congestion. In a system where road use is "free" there would need to be significant government discipline to not heed demands of road users for more roads. Heavy taxes on the purchase of new cars may be a good strategy to dissuade vehicle congestion, with lesser taxes on new EVs and lesser still on used vehicles.
