The article does not claim that we have no control over speeding. We do have control over or speed in numerous ways. The article merely says that signs have little impact on how fast a community goes on any stretch of road... other factors end up being more of a factor. At the same time, road safety is not as strongly tied to the speed of traffic. This article has an attention-grabbing headline (cop says to increase speeds!), but really it's drawing attention to how there are many factors that go into road usage and laws and there are places where people are starting to take these other factors into account. Sounds like a micro-level revolution in how the executive branch of US government operates.
