A San Francisco-based cyclist is suing autonomous driving tech firm Waymo after she was seriously injured when one of the brand’s driverless taxis stopped in a cycle lane and a passenger opened its back door, striking the cyclist and causing her to smash into another Waymo car that was also illegally blocking the bike path.

According to the lawsuit, the Safe Exit system employed by Waymo, formerly known as the Google Self-Driving Car Project, which aims to alert passengers of surrounding dangers and hazards, failed – with the injured cyclist claiming that Waymo knows its cars are ‘dooring’ cyclists.

Jenifer Hanki was cycling in a marked bike lane on San Francisco’s 7th Street on 16 February, on her way home to her flat, when a Waymo taxi carrying four passengers pulled over into the cycle route on the right-hand side of the one-way street, before parking next to a no-stopping sign.

“The kerbside Waymo’s left passenger door suddenly swung open directly in the bike lane,” the 26-year-old said in a statement announcing the lawsuit, according to a report by the San Francisco Chronicle.

“I had no room or time to swerve. With no room or time to react, I crashed violently into the door and interior.”

After she was ‘doored’ by the passenger, the impact of the collision shunted Hanki into a second Waymo that was also illegally parked in the cycle lane, before she landed on the road “disoriented and overwhelmed”.

“As there were no human drivers in Waymo’s vehicles, it exacerbated the chaos,” she continued. “The passengers were visibly confused, the two Waymos remained as they were, obstructing both the bike lane and regular oncoming traffic.”

According to Hanki, the passengers then told the injured the cyclist that it was their first time using Waymo’s autonomous taxi service, and that they were unsure how to report the crash. Hanki says they simply shrugged and left the scene after a few minutes, as other passers-by called for an ambulance.

The 26-year-old was taken to hospital, where she was treated for “serious bodily injuries”, including a brain injury, as well as spine and soft tissue damage.

In the wake of the “violent” crash, which has left her unable to work or ride her bike, Hanki this month sued Waymo and Google’s parent company Alphabet in San Francisco County Superior Court alleging battery, emotional distress, and negligence, while seeking unspecified damages.

According to her lawsuit, one of the safety systems marketed by Waymo is its Safe Exit, which is “supposed to be designed to detect nearby cyclists and pedestrians and notify disembarking passengers to avoid collisions”.

When it first launched as Waymo back in 2016, the firm said its cars are also programmed to recognise cyclists as “unique users of the road”, drive conservatively around them, and recognise common hand signals.

In 2019, the company also released a video showing one of its vehicles predicting that cyclists will move out onto the road to pass a car blocking a cycle lane, with the taxi slowing to allow them to safely move across.

However, Hanki says the company’s Safe Exit system failed, and that Waymo has long known that its cars are ‘dooring’ cyclists.

“Unlike Uber, Lyft, or taxis, where drivers actively monitor traffic and often lock doors or guide passengers to exit safely, Waymo’s system fell short significantly,” she said.

“There was no alert issued in the illegally parked car as according to the passengers. Human drivers prevent accidents every day by assessing real-time risks, something Waymo’s ‘Safe Exit’ system clearly cannot handle.”

While Hanki says she is not against self-driving technology in general, she believes there’s a “gap in accountability” when it comes to safety.

“As technology moves forward, we believe it is crucial for all autonomous car companies to not move forward too quickly,” Michael Stephenson, Hanki’s attorney, added in a statement.

“In the interest of public safety, they must make sure they are adequately testing and refining their technology before subjecting the public to these cars.”

Since the crash in February, 26-year-old Hanki says she is “yet to touch a bicycle because I am afraid of revisiting the same experience”.

“I feel anxious, stressed, and unsafe. Before the crash, cycling was a source of joy and freedom. Now how it feels like I’ve lost that part of myself,” she said.

Hanki isn’t the first cyclist injured at the hands of a Waymo ‘robocab’ in San Francisco. In February 2024, a cyclist was left with “non-life-threatening injuries” after one of the company’s taxis failed to detect his presence and struck him.

According to the company, “the cyclist was occluded by the truck and quickly followed behind it, crossing into the Waymo vehicle’s path. When they became fully visible, our vehicle applied heavy braking but was not able to avoid the collision.”

In November 2019, Waymo secured permission from the California Department of Motor Vehicles for its vehicles to carry passengers without the need for a safety driver who could intervene in the case of a potential collision, making it the first company in the world to secure such clearance.

It has since established itself as the market leader in the United States for self-driving taxis, with commercial operations in San Francisco, Phoenix, Los Angeles, and Austin, and has this week announced that it is planning to test its autonomous ‘robocabs’ in New York City.
