text: Another useful part of the driverless car is it will use half the fuel to run than public transportation does today. Using less fuel is not only environment friendly, but it saves money. This means the driverless car doesnt have to stop as often for gas as a normal car would. The "driver" of the car also doesn't have to drive all the time. Although, the driver does have to be alert the entire time just to be sure that there arent any difficulties. The driverless care will notify the driver if there is a difficulty like "pulling in and out of driveways or dealing with complicated traffic issues."
