Towers of ilium is late to this news party, but we still want to acknowledge that Mexico City has scrapped minimum parking regulations in its zoning code. Concurrent with this, they have adopted regulations that set limits on parking spaces with taxes on spaces constructed above a certain threshold. So, it's still a bit of the nanny state but moving in a refreshingly opposite direction than nearly all zoning codes worldwide.
Great cities do not depend on cars. The depend on people, they depend on density, they depend on diversity. They depend on trucks. Parking spaces are dead weight.
