Alphabet’s self-driving unit, Waymo, is stepping up its expansion into U.S. cities as it crosses a major milestone in its years-long quest to make robotaxis a safe, mainstream transportation option. The company now says its fully driverless vehicles have driven more than 100 million miles without a human behind the wheel—a figure that has doubled in just the past six months.
Milestone Signals Shift from Experiment to Scale
Waymo’s latest figures highlight what it describes as a transition from methodical research to large-scale deployment. Saswat Panigrahi, Waymo’s chief product officer, said the achievement reflects “years of methodical progress now accelerating into rapid, responsible scaling,” adding that expanding into more cities will present fresh challenges that will strengthen the service.
Waymo’s cumulative driverless miles have grown quickly, rising from 25 million in mid-2024 to 50 million by the end of that year, then surpassing 71 million in March. This sustained ramp-up suggests the company is confident in the safety and reliability of its technology, even as regulators and the public continue to scrutinise autonomous driving.
Careful Expansion Amid Competitive Pressure
Currently, Waymo operates its commercial robotaxi service in San Francisco, other Bay Area cities, Los Angeles, Phoenix, Austin, and Atlanta. It has plans to begin fully autonomous ride-hailing in Washington, D.C. next year and is seeking permission to test with trained specialists behind the wheel in Manhattan while preparing to deploy autonomous vehicles in New York City once regulatory approvals are secured.
Though Waymo has generally taken a cautious, phased approach to new markets, the company is facing rising competitive pressure—particularly from Tesla, which is promising a faster timeline.
Tesla and Other Competitors Race to Catch Up
Elon Musk’s Tesla began its own limited robotaxi pilot last month with a small fleet of Model Y SUVs operating in a confined area of Austin, Texas. Despite a history of missed timelines and ongoing safety controversies, Musk has vowed to scale up the service quickly, aiming for launches in multiple U.S. cities by the end of 2025. He also announced plans to roll out in the San Francisco Bay Area within two months, after expanding the Austin service area despite reports of traffic problems and driving errors.
Amazon-owned Zoox is also in the race, developing a vehicle without manual controls such as a steering wheel or pedals, and preparing to launch its first commercial service in Las Vegas this year.
Industry Faces High Costs, Tight Rules, and Scrutiny
While the race for robotaxi dominance is heating up, the road has been far from smooth. Commercializing fully autonomous vehicles has proven more difficult than anticipated, with high development costs, tight local regulations, and safety investigations slowing progress.
General Motors’ Cruise unit, once seen as a top contender, has halted operations following a series of regulatory setbacks and safety incidents. Meanwhile, companies including Waymo, Tesla, and Zoox have all faced federal investigations and recalls in the wake of collisions involving their autonomous systems.
Waymo’s Growing Service and User Base
Despite these challenges, Waymo remains one of the few firms to operate uncrewed taxis with paying passengers in the U.S. As of May 2025, its autonomous vehicles are logging over two million miles each week without a human driver. The company says it has now completed more than 10 million fully driverless trips, up from 5 million at the end of 2024.
Waymo, which began as a modest self-driving research project at Google in 2009 before becoming an independent Alphabet subsidiary in 2016, now sees itself at the forefront of a long-promised transportation revolution. As competition intensifies, the company is betting that its cautious, data-driven approach will allow it to scale responsibly while maintaining public trust in an industry still grappling with questions about safety, reliability, and regulation.
