So you're saying that in your neck of the woods 60+% of drivers aren't texting, the average following distance is >0.5 seconds (ideally always, but at a bare minimum when it's icy out), the average speed through a stop sign is under 20mph, people choose to stop when the sun is blinding them instead of hoping for the best, ...? Suppose drivers are perfect though. Things happen. You can't account for every kid, dog, ... running out in front of you. You don't know when there will be gravel on the road greatly increasing your braking distance. Top speeds of 15-25 are reasonable in a residential area in the sense that anything more greatly increases the chance and severity of pedestrian injury.
