Waymo, Alphabet's self-driving subsidiary, is set to become a major growth engine by leveraging its lead in autonomous miles driven and expanding robotaxi services. Waymo can monetize passengers beyond ride fares by integrating Alphabet's ecosystem, creating additional revenue streams. Competitors like Tesla, GM's Cruise, and Amazon's Zoox lag behind, giving Waymo a near-monopolistic advantage in the U.S. autonomous ride-hailing market.
