text: Driverless cars are coming in the future. In the future, no one will probably need to buy cars because they won't need them. According to Google cofounder Sergey Brin, that will happen. He sees a future with a public transportation system where fleets of driverless cars form a public- transport taxi system. The cars he foresees would use half the fuel of today's taxis and offer far more flexibility than a bus. There are many great things about driveless cars, but there are some bad things as well.
