text: As Google cofounder Sergey Brin envisions in the article, there could be a public transportation system composed of driveless taxis that I think would be greatly beneficial as transportation. They would conserve fuel, which is good for the environment, and offer more flexibility for people who need to commute. Plus, if this system is made true as a public transportation system, it might reduce spending for people who use it and normally might spend more paying for fuel for their car, and/or car maintenance. People spend a lot on making sure their cars are working fine; with driveless taxis as a mode of transportation, you wouldn't have to worry about mechanic and/or fuel costs. A driveless taxi system could be dependable enought that you wouldn't even have to learn to drive or get a car, which could save you not only the cost of a car, but also time.
