"People will drive whatever speed 'feels' like the correct speed on any given road." I mean, I get the psychology behind it. But why do people HAVE to do that? Why can't they just have self-control and self-discipline and not speed? Especially in residential areas? The road might "feel" like it can handle 35-40 mph, but that doesn't make it right. It's just not worth the risk it poses to people, especially kids.
