It's the latest projec t from Google X, the company's skunkworks group headed by Google co-founder Sergey Brin. TWO PEOPLE, NO DRIVERS : The company has already shown off its own self-driving technology, which retrofits existing vehicles made by Toyota and Lexus. However this new version, which was announced by Brin at the Recode conference, is a new design that fits two people, and is driven entirely by computer using a variety of on-board computers and sensors.
