On average, is it cheaper to use a car (including all costs) or use public transport in Melbourne's Central Business District? Hi, our team is debating whether or not we should ban ALL PRIVATE CARS in the CBD of Melbourne. We need this question answered with latest statistics or values, with the value of each cost. e.g. $50 on petrol, etc. We greatly appreciate your answers! Thanks! P.S. Please try to answer as soon as possible.
