You're ignoring emergent alternate modes of travel. Two big ones - electric bikes and app-based ride-sharing (Uber) would greatly benefit from a reduced sea of parking while also allowing transport. This code change will pretty much be focused on malls / shopping centers that currently have more parking space than store space. So new malls or changes to existing will result in a more rational balance than the ocean of tarmac we have now.
