Great article, pretendastronaut. Quoth the article: I suppose the idea is that people don't generally intend to speed on purpose, and if they see they're doing it, they're happy to correct their behavior. I'm glad the county is using the speed feedback sign on my road; too many people drive entirely too fast. However, the implementation could be better. People are being reminded to go 55 in a spot when the safe speed is quite a bit below that. There should be yellow 40 MPH "suggestion" signs as drivers approach the hill, with the same yellow 40 MPH sign attached to the feedback sign. In other spots on the road, 55 is more or less fine. 45 would be better on the two mile stretch where my house is. My neighbor and I discussed asking the county to consider a lower speed limit, but we concluded that the people living on this stretch would be the ones getting tickets.
