Car sharing is the practice of offering vacant seats in your car so that when you embark on a journey there is more than one person travelling in the car. The participants share the costs of the journey, and by reducing the number of vehicles on the road it also contributes to a reduction in our CO2 emissions. By registering and offering your vacant seats in the rockStar car sharing scheme you will be reducing your car running costs, offering a great service to others, and reducing our Carbon Footprint. A win-win position all round!rockStar connects people who need to travel with drivers who have empty seats. Drivers and Passengers can register for FREE with rockStar.
