Alphabet Inc"s (GOOGL.O) self-driving unit Waymo said on Thursday it had partnered with Google"s Maps to let users book fully autonomous ride-hailing services through the app. The service, called Waymo One, will be added in the "ride-sharing and transit" tabs of the Maps app, Waymo said. Waymo One currently offers fully autonomous rides in the East Valley of Phoenix, Arizona. Waymo, formed in 2009 as a project within Alphabet"s Google unit, is widely considered the leader in developing self-driving technology. But is years away from building large-scale businesses, while rival Tesla Inc (TSLA.O) has been selling its semi-automated driving system.
