This is a chicken-and-egg situation. We can't get rid of parking until we have good public transit! We can't have good public transit because all the parking mandates reduce density so much that you can't live without a car!

If you bite the bullet and remove parking, better public transit will come. If you never remove parking, you will never have better transit.

By another measure, removing parking mandates is a very immediate success because it lowers rents by several hundred dollars a month: https://www.planetizen.com/news/2023/11/126192-parking-refor...
