A lot of unnecessary stop signs are there because someone wanted them there. Every subdivision thinks they need a 3 way stop at the entrance, so they start complaining and eventually the local government caves and installs one because it's relatively cheap to install a few signs (and it's easier to ignore the traffic engineer who says it's unnecessary than the dozens of people who live in the subdivision)
