It's true that there is tax money that is spent on infrastructure to support cars, but taxes are also collected from the use of cars through gas taxes and annual registration fees. If you include those taxes and fees it's not obvious how much other taxes are used to subsidize cars.

It will be different in each state, since each state imposes different levels of gas taxes and has different registration fees.

Fuel tax and registration only covers half the cost of roads. Then there’s the cost of all the land for parking. In many cities half of downtown is parking.

Sure but it's rarely free parking, and when it is, it's generally because the property owners are essentially paying for it.
