text: Improving upon current methods of public transportation, Sergey claims that he envisions these fuel efficient, driverless cars forming a "public-transport taxi system" and offering 'far more flexibility than a bus" (Passage 1). This would be an improvement because buses currently have limited range of motion and also move slower and use much more fuel than these new cars would. Also, public transportation would become a more attainable luxury for working class citizens who may usually rely on buses. With driverless taxi-like poublic transportation, a more suitable and enjoyable commute could be possible for those who can only pay a small amount for the service.
