You pay for using the streets in your neighborhood through your HOA or as part of your rent. As you venture out further, business associations provide “free” access around town (paid for by the association members) or you have a monthly subscription—think cable TV package—for the roads covering the areas that you are most likely to use. And as you get on the highway, you pay toll to the corporation that owns it based on vehicle type and distance just as is the case in parts of the country today (only there would be no government involvement).
