Automobile dependence has become a major problem in the United States. People make most of their trips by private vehicle. This has caused us economic, social and environmental problems. Traffic jams caused by overcapacity of cars on the roads lead to lost productivity time, reduced mobility and increased energy consumption. In terms of the social aspect, driving alone and spending more time alone in a car, not everyone can afford to own a car. The majority of CO2, a greenhouse gas, comes from the combustion of fossil fuels, and the main source of it comes from private vehicles. However, the recent phenomenon in the United States, the increase in carpooling, provides an opportunity to address these questions. Car sharing provides access to car-free households, reduces CO2 emissions and reduces the number of cars on the streets. The use of car sharing has been increasing for 15 years in the United States. According to Navigant Research, there were 2.3 million members of car-sharing programs worldwide in 2013. They predict that number will reach 12 million by 2020. Another study by Susan Shaheen2 found that around 800,000 people belonged to car-sharing services in the United States.

With the development of information technology (IT), it has become easy to access and share what we have. Internet services such as Netflix, iTunes and Hulu allow us to share digital content such as movies, music and photographs.
