- remove 90% of street parking
- make the remaining 10% incredibly expensive and time limited to short durations which makes it so that spots are always available for someone that actually needs it for something like moving
- cut down every other road to be impassable by cars or extremely limited
- add wide, safe, protected biking/scooter lanes + bike parking in all the freed up space
- lower speed limits everywhere to cut down on noise and increase safety
I see you studied the work of Donald Shoup, the author of "The High Cost of Free Parking".
