SAN FRANCISCO -- Google plans to open its ride-sharing program to Waze app users in San Francisco this fall, pitting itself against Uber Technologies Inc., The Wall Street Journal reported.
Google in May launched a pilot program around its California headquarters which allowed several thousand area workers at specific firms to carpool together with users of its Waze navigation app, according to the Journal.
Alphabet executive David Drummond on Monday resigned from Uber's board due to increasing competition between the companies.
In 2013, Google invested $258 million in Uber, but now increasingly see each other as rivals.
Google did not respond immediately to a request for comment.
