  Pretty sure it doesn't even go that far most of the time. Around here, there seem to be a few simple rules based on the road's intended use and the area it's in. Lower-traffic residential streets are 25MPH, as are somewhat busier streets in dense areas. Other roads that connect more distant places are 35MPH. And that's about it. One road I frequent has a broad section with parking on both sides, one lane in each direction that would be plenty wide enough for two cars abreast, and a center turn lane. And then there's a narrow section barely wide enough for one lane in each direction, with densely packed houses whose driveways connect straight to the road, and a hill that sharply limits visibility. People tend to go 25MPH in that section and 40+ on the wide section. The limit in both places is 35. About two miles away there's a major connector with 3-4 lanes each way, divided by a median. People often go 50 there. The limit is, you guessed it, 35.
