At a press conference in San Francisco today, Ford Motor Co. president and CEO Mark Fields announced that the company had both acquired a rideshare startup called Chariot and made a significant investment in expanding the region's bike-share program. Ford's sponsorship will see the Bay Area's supply of shareable bikes expand from 700 to 7,000 by 2018, with 1,350 bikes going to the East Bay, and hundreds of new bike-share stations established to distribute the bikes.
