Emails contained in a new legal filing show Uber's former CEO, Travis Kalanick, fretted for years about other companies outstripping Uber in the race to develop autonomous vehicles and use them for ridesharing, and once sought a partnership with Google to ensure that Uber could win the race. In one email, Kalanick complained to Google chief legal officer and senior vice president of corporate development David Drummond (who served on Uber's board for several years before stepping down in 2016) that Alphabet CEO Larry Page was avoiding him.
