Car Sharing Gains Traction

A combination of high energy costs, urban congestion and changes in the way people feel about cars is increasing interest in the idea that a car can be something you borrow and give back, not a cherished possession. The concept of car sharing -- buying the right to use a car instead of the car itself -- has been kicking around for decades. It's an idea that many Americans can relate to at this time of year, when summer vacations can land you in a city where you need a car or a van for just a few hours and renting seems like a hassle.
