text: Not only would the driverless car be safe, but it would also be efficient. Google cofounder Sergey Brin envisions a future with these efficient cars. Brin says that the cars, "would use half the fuel of today's taxis and offer far more flexibility than a bus." The driverless car can be made into an efficient car, saving fuel and allowing for more flexibility than other mediums of public transportation. The cars would be able to take one anywhere while having a better environmental impact. The development of these driverless cars would "fundamentally change the world" for the better.
