My zoning consultant told me that the discussions today within city planning agencies have turned from increasing parking requirements to preparing for the advent of transit (like the  new Expo line extension), the extended use of ride sharing services like Uber and Lyft, and eventually the use of self driving cars.  Planner now see less need for parking spaces and are no longer responsive to communities looking for an increase in parking spaces.  Indeed, Santa Monica and San Francisco have gone the opposite way and have instituted parking maximums in some areas with access to  transit.
