DENVER — A Waymo self-driving vehicle drove through a closed road and into the middle of the South Pearl Street Farmers Market on Sunday morning, raising new questions about how the company's autonomous cars handle temporary street closures and event zones.
The incident occurred around 8:15 a.m., as roughly 160 vendors were preparing their stalls for the day. The robotaxi entered through the market's food truck area, according to Nicole Jarman, the market's production director.
“It entered through our food truck area,” Jarman told KDVR. No injuries were reported, but the intrusion disrupted setup and sparked concern among vendors who were working in a space they believed was closed to traffic.
The market operates on South Pearl Street, a stretch that is typically closed to vehicles during market hours. The robotaxi's presence during setup suggests a gap in Waymo's mapping or real-time awareness of temporary road closures, which are common for farmers markets and other community events across the city.
This is not the first time Waymo vehicles have faced scrutiny in Denver. The city has been a testing ground for autonomous ride-hailing services, and local officials have previously debated how to integrate them safely with pedestrian-heavy events. The incident also comes amid broader national discussions about autonomous vehicle regulation, as federal and state agencies grapple with oversight. Related debates have touched on Denver's legal battles over federal presence at local events, though that case involves immigration enforcement, not autonomous vehicles.
Waymo, a subsidiary of Alphabet, has not yet issued a public statement about the incident. The company has previously said its vehicles are designed to handle unexpected obstacles, but this event suggests challenges remain in recognizing and respecting temporary barricades or event perimeters.
Local vendors expressed frustration, noting that the market had been clearly marked as closed. “We had cones and signs,” one vendor said, speaking on condition of anonymity. “The car just came through like it didn't see them.”
City officials are likely to review the incident, and it may influence future permitting for autonomous vehicles in Denver. The rapid expansion of AI-driven technologies has put companies like Waymo at the forefront of urban transportation, but incidents like this underscore the need for robust safety protocols.
For now, the South Pearl Street Farmers Market will continue its weekly operations, but organizers are considering additional measures to prevent similar incidents, such as physical barriers or coordination with Waymo's local operations team.
The broader implications for autonomous vehicle policy are significant. As cities like Denver become testing grounds, the balance between innovation and public safety remains a contentious issue. Lawmakers have already grilled officials over AI risks, and this event is likely to add to those concerns.
