General Motors (GM) is said to be ending its Ultra Cruise driver assistance program, after years of the technology being called a potential rival to Tesla’s Full Self-Driving (FSD) beta.
As GM attempts to correct issues with its separate self-driving company Cruise following an October accident, the automaker has also been reallocating spending and considering the path forward for its own semi-autonomous driving programs. According to two sources familiar with the matter in a report from CNBC, GM is now ending its Ultra Cruise project after expectations that the system was to launch in the U.S. last year have come and gone.
One of the sources said GM will end the Ultra Cruise program to instead put energy into developing the Super Cruise system, rather than featuring two different ADAS systems with separate naming conventions. While it wasn’t directly commented on, this point seems to have been highlighted by one GM executive in response to the initial report.
“GM continues to expand access to and increase the capability of Super Cruise, our advanced driver assistance technology,” said Darryll Harrison Jr., GM’s VP of Global Tech Communications, in a statement to CNBC, though he declined to comment on Ultra Cruise. “Our focus remains on safely deploying this technology across GM brands and more vehicle categories while expanding to even more roads.”
At the time of writing, GM has not responded to Teslarati’s requests for further comment.
Not to be confused with GM’s more limited Super Cruise system, Ultra Cruise was set to be available in the automaker’s premium vehicles, while the former was being developed for economy-level products. Ultra Cruise was going to offer hands-free driving and a wider set of areas in which the advanced driver assistance system (ADAS) could be used, and it was eventually expected to become capable of driving the car on its own in 95 percent of cases.
Ultra Cruise was also set to use a combination of long-range cameras and short-range sensors, while the system also uses more computing power than Super Cruise. In addition, Ultra Cruise boasted the use of real-time data to govern automobile control—hence its comparison to the Tesla FSD beta.
GM announced plans to debut Ultra Cruise in its Cadillac Celestiq electric vehicle (EV) in a press release last year, after initially announcing the software in 2021.
“Ultra Cruise will cover more than 2 million miles of roads at launch in the United States and Canada, with the capacity to grow up to more than 3.4 million miles,” wrote in its original announcement of the product. “Customers will be able to travel truly hands free with Ultra Cruise across nearly every road including city streets, subdivision streets and paved rural roads, in addition to highways.”
Another similarly named arm of GM, its subsidiary Cruise, has recently been facing significant scrutiny, after the GM-owned company had one of its self-driving vehicles drag and pin a pedestrian in October.
The aftermath of that incident has caused months-long turmoil at the startup, with multiple executives having left ahead of the company laying off around a quarter of the staff. The company also faces both state and federal investigations into its vehicles’ accident response and technology, and GM has halted production of its Origin self-driving van.
During an Automotive Press Association last month, GM CEO Mary Barra said the company was “very focused on righting the ship” at subsidiary Cruise.

Elon Musk handed Grok something no other AI company can get their hands on
Elon Musk says SpaceX will feed engineering data into Grok’s next model, avoiding restricted material.
Elon Musk said Tuesday that SpaceX will feed its internal engineering data into the next major training run for Grok, the AI model now folded into SpaceX following February’s merger. In a post on X, Musk wrote that SpaceX’s “massive corpus of world-class engineering data,” excluding anything restricted under U.S. arms export law, will be added during supplemental training of what he called the “2T run,” a reference to a roughly two trillion parameter model that would nearly double the parameters behind the latest Grok 4.5 that’s rolling out.
SpaceX’s massive corpus of world-class engineering data (excluding material blocked by ITAR) will be added during supplemental training of the 2T run.
This will dramatically improve Grok’s engineering capabilities. https://t.co/BbQEViFByn
— Elon Musk (@elonmusk) July 21, 2026
The excluded material that Musk is referring to would fall under the International Traffic in Arms Regulations (ITAR), which restricts export of technical data tied to defense and space hardware. That likely rules out propulsion specifics for Merlin and Raptor engines along with guidance and control details for SpaceX’s launch vehicles, but leaves manufacturing knowledge, materials science, and Starlink hardware design on the table.
The announcement extends a pattern that has been building since SpaceX’s Nasdaq debut in June, when the company went public with Grok and xAI’s Colossus supercomputer folded into the pitch to investors.
Days after that listing, SpaceX closed its $60 billion all stock acquisition of coding startup Cursor, giving xAI both enterprise software distribution and a stream of real world developer data to train on. Grok 4.5 launched July 8 running partly on that Cursor training data, with Musk describing it as roughly comparable to Anthropic’s Opus 4.7 but faster and cheaper to run.
Feeding SpaceX’s own engineering data into the next AI model follows the same logic Musk has applied across xAI’s sister companies. Tesla supplies real world driving data and manufacturing expertise, X supplies conversational data, and now SpaceX supplies aerospace engineering data built up since 2002.
Musk did not give a release date for the upcoming AI model, referred to elsewhere as Grok 4.6. He has said the two trillion parameter run is in its final training phase and expected to wrap this week.

Tesla expands ridesharing service in California to new hotspot
Tesla has extended its Bay Area ride-hailing service to include pickups and drop-offs at San Francisco International Airport (SFO). The update, shared via the company’s official channels on July 21, allows users in the region to request rides directly to and from one of California’s busiest airports.
The expansion builds on Tesla’s secured limousine permit for SFO operations. Public records show the permit became effective March 20, 2026, and remains active through January 31, 2027. Tesla vehicles operating the service now display authorized limousine permits issued by the City and County of San Francisco.
Our Bay Area rideshare service now goes to SFO ✈️
— Tesla AI (@Tesla_AI) July 21, 2026
Tesla’s ride-hailing program in California relies on Model Y vehicles equipped with Full Self-Driving (Supervised) technology. Human safety drivers remain present in compliance with state regulations, distinguishing the service from fully driverless operations.
The Bay Area geofence covers a broad area spanning north of San Francisco to south of San Jose, offering extensive connectivity across the region.
UPDATE: Elon Musk reveals why Tesla didn’t say ‘Robotaxi’ upon California launch
This SFO addition follows earlier progress at other Bay Area airports. Tesla previously expanded service to San Jose Mineta International Airport (SJC) in late 2025. The company had engaged with SFO, SJC, and Oakland International Airport officials as early as September 2025 to secure necessary approvals for passenger transport.
The service provides a new option for travelers seeking electric, app-based transportation integrated with Tesla’s ecosystem. Rides are booked through Tesla’s dedicated ride-hailing application, which handles matching, routing, and payments. Pricing follows standard ride-hailing models, with potential adjustments based on distance, time, and demand.
Tesla’s California ride-hailing program launched in July 2025 with an initial invite-only rollout in the Bay Area. It started alongside operations in Austin, Texas, marking the company’s second major U.S. market.
The Bay Area remains a primary focus in California, with service centered on high-demand corridors connecting residential, commercial, and now major transportation hubs. This latest airport integration represents a practical step in Tesla’s broader mobility ambitions within the state.
