Even if you did that you'd still need something else. People view cars as a right.
In terms of boiling the frog, I think you already have that. My folks have had the parking on their street halved so it's only on the opposite side. It's a real fucker and has rendered the lamp post EV chargers useless.
But it has created dedicated segregated cycling lanes. And car ownership in the area has been decreasing anyway. When I was a kid getting spots was a fight. Most families had at least 2 cars. Before the bay removal I can't remember there being less than 3 spare spots when I've visited.
Or just having a really good public transport system. Cycliste spent 15 years in Switzerland without a car and, thanks to the fantastic public transport system over there, never needed one. She only bought one due to Covid and no longer wanting to take trains.
