I don't think we're talking about the same kinds of roads.

In an area zoned for residential, e.g. a small town or village, the speed limit will drop and there are noise restrictions. That's quite common, although also quite sparse within the land area.

I've been speaking to unincorporated areas that have no zoning. Many of them are as you described: long, straight roads with mostly-evenly distributed houses over a large distance. These are the types of rural roads that make up the vast majority of land area in the midwest area of the US.
