Nobody is subsidizing your car: as a car owner, you already paid 1) sales tax; 2) yearly registration; 3) yearly property tax; 4) taxes included in gas. Why car owners should be double-triple taxed?

Those costs are minor and not close to covering the cost of car ownership. https://www.theatlantic.com/business/archive/2015/10/driving...

Those don't come close to covering it all. Especially since I don't pay any (4).

Paying to store your car is not a "tax" so it cannot result in being double-taxed. It's a standard payment in exchange for use of property.
