Google Inc. has designed its own self-driving vehicles that transport passengers at the push of a button as it aims to spread the new automotive technology, co-founder Sergey Brin said. Working with automotive partners, the company plans to have 100 to 200 test vehicles that are fully autonomous with extra safety features, Brin said during a conference hosted by technology blog Re/code in Rancho Palos Verdes, California. Google, which up till now had added its technology to other vehicles, plans to start testing the prototypes with drivers this year, he said. http://www.bloomberg.com/news/2014-05-28/google-unveils-company-designed-driverless-prototypes.html
