The chapter starts by describing public transport in Dar es Salaam as ‘functional chaos’. It then critically reviews two thematic literatures, on African cities and on their informal economies, to reveal that references to chaos, dystopia, and their opposites, order and functionalism, are common. The key argument is that a highly contextual understanding of urban informality and of how African cities work is required to avoid overly deterministic structural accounts and romantic celebration of African agency without due attention to structural constraints. The chapter presents the book’s approach: namely a political-economy analysis, centred on class analysis and wary of automatically reading off the political interests of actors from their class position. It argues that neoliberalism and post-socialism are key to understanding Tanzania and public transport in Dar es Salaam, and calls for grounding ‘actually existing neoliberalism’ in a particular context while retaining the analytical power of the concept of neoliberalism.
