You underestimate how much noise cars make. I’m 20 meters from my neighbors and I never hear a peep. Meanwhile, I’m a kilometer from the highway and I can hear always hear it at least a little bit (and a lot when the wind is in my direction). So you have to go really low density, like 1 house per square kilometer and 5 kilometers of dirt road before even reaching a regional road, to go quieter than this, but… unsurpisingly, not many people live there.
