Earlier quoted context omitted.
Car owners are already hugely subsidized. Toll roads cover only a tiny fraction of road maintenance. The rest is paid by taxpayers, even those who do not drive.
> Car owners are already hugely subsidized Around 80% of all commutes in the US are by car. You can't subsidize 80% of the population. Drivers simply pay for their road use through various taxes, and not directly.

I think this is the point, notably because those 'indirect' payments are also payed by non-drivers as well. Hence, the subsidy.
Even within drivers, some are subsidized by others (let alone non-drivers). To illustrate, first: most road wear is from weather [1]. This means any two lengths of similar roads will have about the same upkeep cost regardless of usage (not quite true, but if taking 30 people vs 300, it's about true).
Let's consider 10 miles of road to suburb A with 30 drives, and 10 miles of different but similar road to suburb B with 300 drivers. The city will pay for upkeep of 20 miles, collecting various taxes from 330 people, and those taxes are then spent evenly across those 20 miles. To do this proportionately, without any subsidies, the group of 300 could arguably have those various taxes reduced for them only by 90% and increase the taxes of the 30 people 9 fold. That would be an equitable upkeep system.
The fact the road upkeep payment per person is not equitable, means there is a subsidy (and this situation is not always a bad thing)
