Its not so simple as “I paid I, so I do what I want”. Are roads funded exclusively from tax collected from car taxes? Aren’t bicycle and public transport users also funding roads also? Even if indirectly, by going to a shop that use those roads for supplies. As far as I heard, roads cost a LOT to maintain (and more to build). 77 billion might be a small bucket in the ocean depending on the country. This is public space, your freedom to drive a car impacts my commute time by bus.
