Evidence: Google's cars that can drive independently under specific conditions have "driven more than half a million miles without a crash." The driverless car has not been fully developed, yet already Google's cars have successfully driven over a long distance without any accidents. Technology is constantly improving, and so will safety. Google's cars have position-estimating sensors, automative radar sensors, and even a rotation sensor on the roof. As these senors are improving, it is also making "driving safer and also leading to cars that can handle more and more driving tasks on their own." Once the driverless car is completed, it should have the sensors and technology to keep drivers safe, more than the ability of an actual human drivers to keep themselves safe. The advanced technology is not only a dream, but is slowly becoming a reality. Sebastian Thrun, founder of the Google Car project, "believes that the technology has finally begun to catch up to the dream." The driverless car is a ensured success, and with the development of the driverless car, comes the ensured safety of the driver.
