But parking at home? There's a straight line connection between the car owner who uses the space and the cost of the space. I shouldn't expect the government to pay for my parking any more than I should expect the government to pay for my house. In fact, paying for people's houses would be a lot more reasonable, since people need housing, but don't need parking.
I can't come up with any such counterarguments for public parking. It doesn't benefit non-drivers in any way, and the people it does benefit mostly don't need public assistance.
Edit: who pays majority of taxes for road use? It's car owners. You have cheap buses only because car owners paid majority of the bills for road network maintenance and development.

Gas taxes don't cover all road expenses. I looked at Virginia's data (since that's where I live) and nearly as much road construction/maintenance money comes from normal sales taxes as comes from gas taxes. Another substantial chunk comes from the Federal government, and the Feds pay out substantially more than they receive from the Federal gas tax.
