Driving in Sao Paulo is always an adventure, and it is far more difficult and dangerous than driving in the US. Besides having many roads in bad or poor condition, especially in the poorer areas of the city, there are many other problems: poor driving skills, (many people pay off someone to buy their drivers license instead of learning to drive), a lack of enforcement of rules and laws, an excess of cars (over 6,000,000 cars every day in Sao Paulo), smaller and crowded roads,... Another well known problem is the intensely crazy driving of the "motoboys", which are people who drive motorcycles. Many of them are deliverymen, and they are everywhere. They essentially have no rules, and they are famous for driving extremely fast and for weaving in and out between cars. On average there are 2 motoboys who die every day in Sao Paulo.
