Mazda, the Japanese car maker will pay their workers an average of $ 12 extra if they walk (at least 2.5 miles a day) to work. This is a good initiative from an employer and makes a statement that addresses both the health issues of their employees and environmental issues. That this comes from an automobile manufacturer, makes it all the more powerful.
I can never imagine something like this happening in the United States. Here it is the birthright of all citizens to own and drive a car, and it is considered a crime to NOT drive to any place more than 100 m. away.
