TOKYO (AFP): US electric car maker Tesla is developing technology that could see vehicles run on “full auto pilot” in as little as five or six years, according to its chief executive Elon Musk. The colourful entrepreneur said his firm was stepping on the accelerator in the race against rivals such as Google and Volvo to create a driverless car, which could revolutionise the road by drastically cutting mortality rates. “The overall system and software will be programmed by Tesla, but we will certainly use sensors and subcomponents from many companies,” Musk told.
