Sao Paulo - In the streets of Sao Paulo, traffic barely moves in rush hour. The endless stream of cars moves at a snail's pace on 10-lane avenues.
Some 6 million cars, buses, motorcycles and trucks daily plough through the city of 20 million people, and an estimated 800 new vehicles join the frenzy every day. On bad days, officials estimate traffic jams reach lengths of more than 220 kilometres. The few underground lines and the 15,000 buses are full. No wonder people with the necessary cash evade the streets by taking to the air.
Sao Paulo is a city with the most helicopter taxis in the world and the highest concentration of helipads.
