Lagos is chaos theory made flesh and concrete. It’s the largest city in Africa, with wall-to-wall people, bumper-to-bumper cars, noise and pollution beyond belief, a crime rate out of control, and public utilities that are simply incapable of coping with the demands of the huge population. Elevated motorways ring the city, jammed with speed freaks and traffic jams (‘go-slows’) on top, and tin-and-cardboard shacks underneath.
