Waymo Kicks Off Testing in Philadelphia with Human Safety Drivers

Waymo, the self-driving unit of Alphabet Inc., announced that it has begun testing its autonomous vehicles in Philadelphia, signaling a key step in the company’s efforts to expand its presence in major Northeastern cities. The vehicles, equipped with Waymo’s autonomous driving system—Waymo Driver—will be manually operated by trained safety drivers as they navigate the city’s complex roadways.

Testing began this summer and will continue through the fall, with Waymo’s limited fleet gathering data on urban traffic patterns, road conditions, and local infrastructure.

Why Philadelphia?

Waymo described Philadelphia as a city with “grit and spirit,” announcing its arrival with a characteristically playful message on X: “This city is a National Treasure… Our road trip continues to Philly next.” But behind the branding lies strategic intent.

Philadelphia, the sixth-largest city in the U.S., offers a highly varied driving environment that includes narrow colonial streets, multi-lane freeways, and heavily trafficked urban corridors. These conditions provide a critical proving ground for autonomous systems aiming to scale across the country.

A Waymo spokesperson told CNBC that its test fleet would be visible “at all hours throughout various neighborhoods,” including North Central, Eastwick, University City, and along the Delaware River. The aim is to collect mapping data and evaluate how Waymo’s autonomous technology adapts to regional driving behaviors and infrastructure differences.

Part of a Broader Roadmap

Philadelphia’s inclusion in Waymo’s growing test footprint is part of what the company calls its “road trip” strategy—a phased approach that involves manually driven vehicles collecting detailed environmental and traffic data before autonomous operations are considered.

The move follows similar manual testing launched in New York City last month, where Waymo filed for permits to operate with trained specialists behind the wheel. Autonomous vehicle deployment in NYC remains limited due to state laws prohibiting fully driverless operations.

Waymo One, the company’s commercial ride-hailing service, is currently active in Phoenix, San Francisco, Los Angeles, and Austin, delivering over 250,000 paid rides per week. Fully autonomous services are in the pipeline for Atlanta, Miami, and Washington, D.C., with rollouts planned for 2026.

Financial and Strategic Context

Waymo’s expansion comes at a critical time for Alphabet, which is under mounting pressure to monetize its artificial intelligence and autonomous vehicle ventures amid increased infrastructure spending. In 2024, Alphabet’s “Other Bets” segment—home to Waymo and other non-core initiatives—generated $1.65 billion in revenue, up from $1.53 billion in 2023.

However, losses deepened to $4.44 billion in 2024, compared to $4.09 billion the previous year, reflecting the high cost of scaling complex technologies like autonomous driving.

Waymo’s presence in Philadelphia will serve not only as a technical testbed but also as a potential signal of the company's long-term commercial ambitions in the Northeast. Successful data collection and performance in cities like Philadelphia and New York could accelerate regulatory approval and open the door for Waymo One to enter new, densely populated markets.

Looking Ahead

As the fall testing period continues, the key question remains: how soon will Waymo be ready to offer autonomous rides in the Northeast? While full deployment is still some distance away, the expansion into Philadelphia is another calculated move in Waymo’s mission to make driverless transportation a mainstream reality.

By embedding itself into the urban core of one of America’s oldest and most complex cities, Waymo is laying the groundwork for the next frontier in autonomous mobility—one data point, street corner, and traffic light at a time.
