Reading a Jarod Diamond book, always enjoy his work. Just so many fascinating things about other cultures. Came across a little gem that highlights the importance of researching local customs before visiting, especially in less well travelled parts. If you are driving in rural New Guinea and you hit a pedestrian, even if it was 100% unavoidable, don't stop to render aid! Drive directly to the nearest police station and turn yourself in. Because if you stop, good chance bystanders will simply kill you, and possibly your passengers as well. Yikes.
