Lift sharing, ride-sharing, car-sharing or carpooling - it doesn't matter what you call it, it’s two or more people sharing a car to get from A to B rather than driving alone. Now this prospect might scare you to begin with, especially if you are a shy person, however, not only will you gain friendship, the benefits soar way beyond – think of the amount of the money you could be saving by only driving to work for one week out of two.
