This timelapse video shows exactly what it can look like if you have no traffic lights in place. You know, pesky government control stuff like traffic lights. This is the intersection at Meskel Square in Addis Ababa, Ethiopia.
From the video description:
Meskel Square. The nerve center of Addis Ababa, is often the site chosen by the Ethiopians for festivals and celebrations but also is a chaotic crossroads thousand vehicles cross daily.
