If you want to get rid of minimums per building look at the upgrade path. Parking /silos/ owned by the city, right at transit transition hubs, at the edge. The use case is driving in from the 'savage lands', having ample (free (paid for the same way roads are)) parking, and transferring to the local rail/bus/people-mover-belt system of the dense urban core.
