Mexico City
Don't Take The Ride: Those green-and-white VW Beetles may be among the world's cutest taxis, but sad to say, Mexico City is home of the "express kidnapping," during which your taxi-driving thief will take you to an ATM, rough you up, and force you to withdraw money. The problem is so well known that the Department of State maintains a travel warning about it. Only take taxis that you've contacted in advance or that you hail at a regulated taxi stand, called a "sitio."
