From this video I get the sense that the pace of development is the extreme edge of rapid and the extreme edge of slow. 

Development patterns in many African cities look surprisingly similar to American cities. The land usage is mixed between areas of high density housing, low density housing, single family homes, multi family homes, high rises, auto-oriented boulevards, pedestrian oriented commercial streets, auto-oriented businesses, all in various states of cohesion or non-cohesion. This is mad different from much of what you will find around the World, where cities have endless neighborhoods consisting of typical high to super high population density. High density is typical for big cities in most of the World, except America. Interesting to see similarities from a place so different.
