Waymo Refutes Claims of Remote Driver Usage Following Viral Senate Testimony

Waymo has stepped up to clarify its use of remote assistants for its robotaxi service following a viral Senate hearing featuring one of its executives. In a letter to Senator Ed Markey, Ryan McNamara, Waymo’s head of global operations, detailed the company’s remote assistance framework, including the distribution of its workforce.

According to McNamara, Waymo has around 70 remote assistance agents available at any moment, split evenly between the US and the Philippines. These agents are there to provide guidance only when the automated driving system requests it, acting on an event-driven basis. He emphasized that these agents do not control or drive the vehicles directly.

The company faced scrutiny after reports suggested that the Senate testimony revealed a troubling secret about its operations. During the hearing, Markey questioned Waymo’s chief safety officer, Mauricio Peña, about the presence of overseas workers. Markey likened the situation to Waymo “phoning a human friend for help,” which led to misunderstandings about the role of remote operators.

In his letter, McNamara clarified that these agents do not oversee the vehicle’s operations or monitor live feeds from the robotaxi cameras. Instead, the automated driving system reaches out to remote assistance when it encounters uncertain situations, providing an extra layer of safety. These interactions are typically brief, lasting only a few seconds.

McNamara assured Markey that all remote assistants in the Philippines are licensed drivers, fluent in English, and have passed drug tests. They undergo extensive training tailored to their specific roles, and their performance is closely monitored. He also noted that the latency between the vehicle and the remote assistant is minimal, approximately 150 milliseconds for US-based centers and 250 milliseconds for those abroad.

The remote assistants handle tasks ranging from simple vehicle checks to suggesting routes around obstacles. They are separate from Waymo’s Event Response Team, which is deployed in the event of crashes or safety incidents, and all ERT members are based in the US with specialized training.

While these remote assistants do not drive the vehicles, there is a specific tool for rare situations where a vehicle needs to be moved from the shoulder of a highway. In such cases, an ERT agent could instruct the vehicle to move forward at a slow speed to exit the travel lane. So far, this tool has only been used in training scenarios.

McNamara did not disclose the exact number of requests made between the automated driving system and remote assistants per mile, deeming the figure “not material,” but assured that detailed records are kept.

He stressed the importance of distinguishing Waymo’s operations from those of other autonomous driving companies that utilize teleoperators or remote drivers. For instance, Tesla employs remote drivers as a backup for its robotaxis, while other companies, like May Mobility, follow Waymo’s model of having remote assistants provide suggestions when needed.

Waymo’s operations are under heightened scrutiny following several safety incidents, including a power outage in San Francisco that left robotaxis stranded and an incident where a child was struck by a robotaxi in Santa Monica. A previous incident involving a Waymo robotaxi running a red light was attributed to an incorrect prompt from a remote assistant. This comes amid growing concerns about the implications of driverless cars and potential job losses due to AI.

Phil Koopman, an expert in autonomous vehicles, noted that the key issue isn’t whether remote human drivers exist, but whether the safety measures in place are adequate. He pointed out that while Waymo claims to have rigorous operational practices, there is a lack of independent oversight to ensure these claims are met in practice.

As robotaxi services expand, many people remain unaware or confused about the different levels of autonomy and the role of human assistance. Waymo’s vehicles are often classified as Level 4, meaning they can handle all driving tasks under certain conditions, but this does not eliminate the need for human intervention. Level 5 autonomy, where a vehicle can operate anywhere without human help, is still considered a distant goal.

Update February 18th: A previous version of this story inaccurately stated that Waymo employs a total of 70 remote agents; this figure refers to those on duty at any given time, and the total number of agents has not been disclosed.
