My city, Utrecht, in the Netherlands is quite close this. No cars in the city center, no diesel vans for delivery, only busses and taxis can drive in certain roads in the center, bikes have priority on most roads cars can drive outside the center, mow they are reducing the speed limit to 30km/h everywhere in the city (following Amsterdam on this), and they are building a new car-free neighborhood for 40k people with no parking spaces and car roads.
