China has by far the worst traffic in the world. Traffic jams in some massive cities have been known to last for days.
Most larger cities anywhere in the world will have bad traffic. Bristol and Belfast in the UK come to mind first being larger areas to have traffic congestion. Of course travelling in off hours can typically help.
Detroit is the worst overall city. For larger cities, Chicago is statistically pretty bad. Chicago has some of the worst stats involving taxes, unemployment, youth violence, traffic congestion, pollution, corruption....on and on.
Tampa is not one of the worst cities. However, it is not one of the best cities either.
