Hanoi, Boomtown Vietnam

Hanoi is a city on the move. Bicycles, motorbikes and taxis crowd the well-maintained streets.

Here, ridesharing means packing three people and their cargo on a single moped. The city has a single traffic rule--the most aggressive driver wins the right of way. Our fixer, Thuy, tells us that a few years ago, the traffic mostly consisted of bicycles, but today motorbikes rule.

Cell phones are a necessity and iPods common.

The Vietnamese don't need an SUV to move their goods around. A bicycle or moped does just fine.

No car? No problem.
