Obviously these things take time to carry through. When you half the parking space, you don't suddenly half the amount of cars. Over time people frustrated with the parking, the fines for parking in wrongful areas and the walking distances when parking further from home, will sell their car, and over time fewer people who didn't have a car yet will buy one than they otherwise would in a world of ubiquitous parking. Gradually this reduces the amount of cars and displaced parking. If you build new housing without parking for new inhabitants, you don't have that inherent excess of cars per parking spot. You might have some excess still but not nearly as much. The biggest solution though is to offer alternative transport, first, and then removing, reducing or making more expensive the parking infrastructure. Here in Amsterdam the city has been removing parking and hiking up parking fees quite rapidly. But it was after establishing ubiquitous, separated, safe cycle paths everywhere, a decent tram, bus system and metro, 8 train stations (in a city of just 1 million) and another relatively high-speed underground light rail project in the works today, as well as public-transport's rentable bicycles and mini electric cars (which, due to sharing, is getting iirc about ~20 users for the space of one traditional parking spot). In Amsterdam I've never owned a personal car and won't ever need to. But having lived in America, I can't imagine that to work.
