These are the cities with the worst noise pollution

Motorcycle couriers lane split between cars in Sao Paulo September 6, 2012. Dying at the rate of three per day, according to official statistics, Sao Paulo's approximately 200,000 registered motorcycle couriers, nicknamed either motoboys or mad dogs, are the terror of drivers. Motoboys in the city bully drivers into giving them the right of way as they race along the corridors formed between the rows of vehicles stuck in heavy traffic, making them their exclusive high speed corridors.
