bloomberg: Google 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 yesterday hosted by technology blog Re/code in Rancho Palos Verdes, California. Google, which until now had added its technology to other vehicles, plans to start testing the prototypes with drivers this year, he said.
