What? If the law that requires an absolute minimum number of parking spaces hasn't increased, then the total number of parking spaces hasn't increased? People can build more parking spaces than the parking minimums? Also, Parking minimums themselves increase parking for new businesses? Any new structure you build being subject to parking minimums contributes to the loop I'm describing.
