A Lucid Gravity robotaxi equipped with Nuro’s autonomous driving technology was spotted on public roads in Santa Clara, California, as the program moves from closed-track testing to real-world validation.
A Reddit user photographed the vehicle near Levi’s Stadium, home of the recent Super Bowl, in what appears to be the first public sighting of the Lucid-Nuro robotaxi operating in traffic.
“Near Levi’s stadium, the neighborhood is very busy today, I saw a Rivian R2 as well,” the user wrote.
The robotaxis, which will be available exclusively through Uber‘s app, are planned to begin operation in the Bay Area later this year before expanding to major US cities.
CES Unveiling
Lucid unveiled the production-intent robotaxi at CES in January, showcasing features including real-time displays showing what the vehicle sees and plans to do, as well as exterior LED screens displaying rider initials and trip status.
The Gravity platform required minimal modifications to accommodate Nuro’s sensor array.
“Lucid didn’t have to redesign the body structure to integrate Nuro’s sensor halo as it mounts perfectly using the existing roof rack mounts,” the company said in a February 4 blog post.
Closed Track — Public Roads
The public testing follows months of validation at Nuro’s Las Vegas proving ground, a facility the SoftBank-backed company opened in late 2021 specifically for developing autonomous driving technologies.
Nuro, which counts SoftBank, Chipotle, and Toyota’s Woven Capital among its investors, is responsible for integrating autonomous systems into Lucid‘s vehicles.
At the closed track, Nuro tests edge cases including pedestrians emerging from occluded areas at night, unpredictable cyclists, construction zones, traffic signal outages, and sudden merges.
Nuro completed installation of its Level 4 autonomous systems on the first Lucid-based robotaxi in under two months last year.
The prototype was built at Lucid‘s Arizona plant before being transported to Nuro’s Newark, California headquarters for sensor integration.
Lucid said last week that sensor installation will eventually move to its Arizona factory as production scales.
“Later this year, all these sensors and equipment will be installed as part of the assembly process at our facility in Arizona,” the company wrote in a blog post.
Uber Partnership
Uber invested $300 million in Lucid last year and placed an order for at least 20,000 Gravity SUVs to be delivered over six years.
The ride-hailing company also invested an undisclosed amount in Nuro as part of an August funding round that included Nvidia and totaled $203 million.
While the Gravity’s average selling price in the US is approximately $120,000, Lucid has not disclosed the pricing structure for the Uber fleet order.
Lucid interim CEO Marc Winterhoff said last year that the company aims to exceed the initial 20,000-unit commitment.
“Twenty thousand is a good number. But at the same time, when you look at the details of the agreement, it’s over six years. It’s not that big of a number,” Winterhoff said.
“We want that number to be much bigger than that,” the interim chief added.
Production Ramp
Lucid faced significant production challenges with the Gravity throughout 2025, including chip shortages and fires at an aluminum supplier.
Output has ramped up significantly in the final quarter of the year, with Lucid doubling output and meeting its twice reduced annual production guidance of 18,000 units.
