And don't forget the insane "free" neighborhood resident on-street parking.You are free to think that, but from a public-policy standpoint, we need to make personal car use in the "core" more expensive because it bogs down other, more-valuable modes.
Other modes are more valuable for urban mobility. Buses, bikes and plain-old walking on the sidewalk, in particular, do a better job of moving people per lane-mile of city street (and demand far less sq ft of parking space per user too). Transit is more valuable too, and we need to identify ways of funding its expansion.
Higher parking rates are a double win: reducing congestion and paying for increased usefulness of other modes.
Ideally, the revenue from higher parking rates (both from meters and from taxes on private parking) should work the same as a congestion charge: the money should pay for better shared modes (transit) and the reduction in traffic lets all traffic that remains move more freely.
