Waymo, a subsidiary of Alphabet Inc., announced on Wednesday its plans to introduce robotaxi services on highways across San Francisco, Los Angeles, and Phoenix. This marks the Google subsidiary’s inaugural effort to broaden its operations amid increasing competition in the autonomous driving sector, both domestically and globally.

Initially, Waymo will provide highway rides to select early access users. The company stated, “If the freeway route is considerably quicker, we can synchronize it with freeway travel to deliver a faster, smoother, and more efficient ride.”

Currently, Waymo operates in select areas of the San Francisco Bay, with plans to expand into San Jose, including the Mineta San Jose International Airport, which is the second largest airport in its service zone after Phoenix Sky Harbor.

This development comes as Tesla broadens its rob-taxi service with safety monitors and drivers, while Amazon-backed Zoox is providing complimentary robo-taxi rides around the Las Vegas Strip.

Waymo stands out as the sole company in the U.S. offering a paid robotaxi service with over 1,500 vehicles that operate without safety drivers or in-vehicle monitors. The company began charging for rides in Phoenix back in 2020, nearly 11 years after its inception as Google’s self-driving car initiative.

Over the years, Waymo has expanded gradually, but it, like its competitors, is currently under federal investigation for erratic driving behavior.

Although highway driving is generally less complicated compared to city navigation, it introduces a range of new challenges that require higher-speed maneuvering, such as merging and exiting. Self-driving cars find urban environments particularly tough due to numerous pedestrians, frequent intersections, and unpredictable conditions. However, errors or failures at high speeds on highways can lead to severe consequences. The company mentioned collaborating with local highway patrols and safety agencies to develop new protocols for highway travel.

While Tesla has long provided driver-assistance features on highways, this initiative positions Waymo as the first company to offer fully driverless operation on highways.
