text: First, the development of driverless cars can bring efficiency to the day-to-day life of an average human. The vision for these cars is that they will be a part of, "a public-transport taxi system. The cars [Google cofounder Sergey Brin] foresees would use half the fuel of today's taxis." The United States is one of the largest sources of oil consumption, and we tend to get all of our gas from other countries. With the direction these cars seem to be taking, we'd not only reduce the amount of gas we use in the United States, but in the entire world. We wouldn't be emitting nearly as much air pollution either. The benefit of public transportation is also significant due to the fact that, it too, decreases all of these factors. Based on my knowledge, most European countries tend to consume a lot less oil than the United States because they use public transportation. It's a lot more efficient than everyone owning an individual car and driving. By supporting the development of driverless cars, all of these imaginable benefits for the efficiency of transportation can become a reality.
