This video podcast examines whether an auto-sharing program in Paris can, in fact, help reduce automobile usage. Paris' citywide bike-sharing plan, Velib', has been so successful that the mayor wants to create a similar system for cars. Autolib', as it would be called, could offer a reliable and affordable alternative to driving personal vehicles in the city's congested streets. Some, however, feel that giving people the option to use a car in lieu of public transport is a step backward.
