text: To begin, driverless cars are being designed to be used as a transporation system. Today all forms of public transportation are driven by people. Those people are entrusted with the safety of their passengers. Having driverless cars as a form of public transportation would be unreliable and use more gas, because more people would need rides. Google cofounder Sergey Brin imagines less people buying cars and using the driverless publc transportation. This would put pedestrians in vehicals without a trusted driver. This is one reason why driverless cars are not beneficial.
