text: First of all, driverless cars would become just like a public-transport taxi system, only better. These cars can better improve how we drive, more economically. The smart cars now only "use half the fuel of today's taxis and offer far more flexibility than a bus". This will help the environment greatly, because with all the pollution from old cars and diesel semi-trucks, our air quality will not be so good if we do not do something to make it better. These driverless cars will help the environment, and it will not add to the problems we have now. With the cars only getting better, the future driverless cars will only advance more as car manufacturers figure out ways to make travel easier.
