What can I do to make people not drive by my house as much?  I live at the end of a cul de sac and shouldn't have ANY traffic down here since it's just my house, but people come down here all the time to turn around and go out of the neighborhood. What can I do?  Can I  dig up a big pothole in the road or something/

It's not a good idea to damage public property just to get some annoyance out of your system, but I can point you to a research paper that analyzed solutions people found for decreasing the risk of this problem. Some people have considered putting up speed bumps to deter drivers from coming into the cul-de-sac, but that's probably a bad idea too.
