Ride services using self-driving vehicles could slash by more than half demand for owner-driven sedans in the United States by 2030, according to a study released Monday by consulting firm KPMG that used cellphone data to map commuter travel in three large U.S. cities.

The KPMG researchers forecast that ride services using self-driving vehicles will launch first in densely populated urban and suburban areas it calls "island markets." Alphabet's Waymo self-driving car unit and General Motors have said recently they intend to launch pilot autonomous ride sharing services in limited urban or suburban areas.
