text: My third reason that I am for driverless cars is that they have a gas milage that is twice as good as the cars that people drive today. One example from the text is, "The cars he foresees would use half the fuel of today's taxis and offer far more flexibility than a bus" (Driverless Cars Are Coming 1). Not only will these cars have a better gas milage, but they will also be able to get to more places than a city bus would be able to go. If driverless cars were used instead of regular cars, the world would use half as much gasoline as it already does. That would mean that the world will be able to us gasoline for twice as long and it will take the world twice as long to run out.
