6. Lagos, Nigeria
The World Bank once gave Lagos $150 million to build new roads. What did the country do instead? They bought buses. So now it’s full of poor roads packed with too many cars and even the local residents are referring to peak-hour driving as “go slow.” At least someone is finding a bright side to this; Governor Babatunde Fashola called the daily gridlock a “blessing” and a sign of “economic prosperity” back in 2010. Sure thing.
