To save money a lot of people in China, India, Turkey, Mexico and Brazil are car sharing. Just like when people rent a car on vacation, local people are renting. This is a great idea because generally having a car it would cost to buy it, then tax the car, it all adds up.
So when people need a car for the weekend or for a special occasion they simply hire one, not only does it save money and make it for convenient for them people. It helps the environment as the people wouldn’t be using the car every day, just at certain points. Personally I think it’s a fantastic idea it still helps to reduce the carbon footprint, and save people money, its the two thing people want.
