Uber forced to stop self-driving pilot program in San Francisco by DMV
No longer will Uber’s self-driving cars be seen on San Francisco’s streets. The company announced on Wednesday that it was ending its autonomous car service, which began just a week ago, after clashes with state regulators and amidst much public concern.
The state’s Department of Motor Vehicles revoked Uber’s registrations, saying they “were improperly issued for these vehicles because they were not properly marked as test vehicles.” While competitors such as Tesla Motors, Google, and Nvidia have complied with state testing requirements, Uber claimed it didn’t need a permit, as it says its cars were not fully autonomous.
The sixteen Uber Volvo XC90s were equipped with a suite of roof-mounted sensors and dual driver controls. Two humans were onboard, one who was required to keep hands on the steering wheel at all times and another who monitored the technology.
Self-driving vehicles steer and brake independently but generally operate with a human in the driver’s seat who is prepared to assume driving responsibilities should the situation merit it. California law defines autonomous vehicles as those that drive “without the active physical control or monitoring of a natural person.” Under threat of legal action, Uber shut down the pilot program.
From the moment that Uber’s small self-driving fleet entered San Francisco’s traffic patterns, controversy arose. Videos emerged of Uber pilot cars running a red light and stopped in the middle of an intersection. Uber blamed red light incidents on human driver error, not the cars’ technology.
Brian Wiedenmeir, executive director of the San Francisco Bicycle Coalition, wrote on the organization’s website that, prior to Uber’s official launch, he encountered self-driving Ubers make multiple illegal and unsafe “right-hook” turns across bicycle lanes. “Those vehicles are not yet ready for our streets.” Uber, however, countered, explaining that a software fix for right hooks “has already been fixed operationally.” In other words, the two humans aboard were instructed to assume vehicle control when making these more complicated turns.
San Francisco Mayor Ed Lee commended the DMV for taking enforcement action against Uber. “I have always been a strong supporter of innovation and autonomous vehicle development and testing,” he wrote Wednesday in an emailed statement, “but only under conditions that put human, bicyclist, and pedestrian safety first.”
In a letter to Uber, DMV Director Jean Shiomoto assured the company that the department is a proponent of autonomous technologies. “We are committed to assisting Uber in their efforts to innovate and advance this ground-breaking technology.”
“Uber is welcome to test its autonomous technology in California like everybody else, through the issuance of a testing permit that can take less than 72 hours to issue after a completed application is submitted,” a DMV spokesman wrote in an emailed statement. “The department stands ready to assist Uber in obtaining a permit as expeditiously as possible.”
“We’re now looking at where we can redeploy these cars,” an Uber spokeswoman said in a provided statement, “but remain 100 percent committed to California and will be redoubling our efforts to develop workable statewide rules.”
Uber’s reveal of its San Francisco self-driving car rollout was quite the spectacle, intended to position the company as a keen rivals to its competitors. Anthony Levandowski, vice president for Uber’s self-driving technology, blogged that “the promise of self-driving is core to our mission of reliable transportation, everywhere for everyone.”
Now Pittsburgh is the only U.S. city which allows Uber’s self-driving carshare service. No major incidents have been reported from the Pittsburgh test program, which began in September.

Tesla says its Texas lithium refinery is now operational and unlike anything in North America
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
Tesla has confirmed that its Texas lithium refinery is now operational, marking a major milestone for the company’s U.S. battery supply chain. In a newly released video, Tesla staff detailed how the facility converts raw spodumene ore directly into battery-grade lithium hydroxide, making it the first refinery of its kind in North America.
Elon Musk separately described the site as both the most advanced and the largest lithium refinery in the United States.
A first-of-its-kind lithium refining process
In the video, Tesla staff at the Texas lithium refinery near Corpus Christi explained that the facility processes spodumene, a lithium-rich hard-rock ore, directly into battery-grade lithium hydroxide on site. The approach bypasses intermediate refining steps commonly used elsewhere in the industry.
According to the staff, spodumene is processed through kilns and cooling systems before undergoing alkaline leaching, purification, and crystallization. The resulting lithium hydroxide is suitable for use in batteries for energy storage and electric vehicles. Tesla employees noted that the process is simpler and less expensive than traditional refining methods.
Staff at the facility added that the process eliminates hazardous byproducts typically associated with lithium refining. “Our process is more sustainable than traditional methods and eliminates hazardous byproducts, and instead produces a co-product named anhydrite, used in concrete mixes,” an employee noted.
Musk calls the facility the largest lithium refinery in America
The refinery’s development timeline has been very impressive. The project moved from breaking ground in 2023 to integrated plant startup in 2025 by running feasibility studies, design, and construction in parallel. This compressed schedule enabled the fastest time-to-market for a refinery using this type of technology. This 2026, the facility has become operational.
Elon Musk echoed the significance of the project in posts on X, stating that “the largest Lithium refinery in America is now operational.” In a separate comment, Musk described the site as “the most advanced lithium refinery in the world” and emphasized that the facility is “very clean.”
By bringing large-scale lithium hydroxide production online in Texas, Tesla is positioning itself to reduce reliance on foreign refining capacity while supporting its growth in battery and vehicle production. The refinery also complements Tesla’s nascent domestic battery manufacturing efforts, which could very well be a difference maker in the market.

Tesla Optimus V3 gets early third-party feedback, and it’s eye-opening
Jason Calacanis’ remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot
Angel investor and entrepreneur Jason Calacanis shared some insights after he got an early look at Tesla’s upcoming Optimus V3. His remarks, which were shared during a discussion at CES 2026, offered one of the first third-party impressions of the yet-to-be-unveiled robot.
Calacanis’ comments were shared publicly on X, and they were quite noteworthy.
The angel investor stated that he visited Tesla’s Optimus lab on a Sunday morning and observed that the place was buzzing with energy. The investor then shared a rare, shocking insight. As per Calacanis, Optimus V3 will be so revolutionary that people will probably not even remember that Tesla used to make cars in the future.
“I don’t want to name drop, but two Sundays ago, I went to Tesla with Elon and I went and visited the Optimus lab. There were a large number of people working on a Sunday at 10 a.m. and I saw Optimus 3. I can tell you now, nobody will remember that Tesla ever made a car,” he noted.
The angel investor also reiterated the primary advantage of Optimus, and how it could effectively change the world.
“They will only remember the Optimus and that he is going to make a billion of those, and it is going to be the most transformative technology product ever made in the history of humanity, because what LLMs are gonna enable those products to do is understand the world and then do things in the world that we don’t want to do. I believe there will be a 1:1 ratio of humans to Optimus, and I think he’s already won,” he said.
While Calacanis’ comments were clearly opinion-driven, they stood out as among the first from a non-Tesla employee about Optimus V3. Considering his reaction to the humanoid robot, perhaps Elon Musk’s predictions for Optimus V3 might not be too far-fetched at all.
Tesla has been careful with its public messaging around Optimus V3’s development stage. Musk has previously stated on X that Optimus V3 has not yet been revealed publicly, clarifying that images and videos of the robot online still show Optimus V2 and V2.5, not the next-generation unit. As for Calacanis’ recent comments, however, Musk responded with a simple “Probably true” in a post on X.

Tesla taps Samsung for 5G modems amid plans of Robotaxi ramp: report
The move signals Tesla’s growing focus on supply-chain diversification and next-generation communications as it prepares to scale its autonomous driving and robotaxi operations.
A report from South Korea has suggested that Samsung Electronics is set to begin supplying 5G automotive modems to Tesla. If accurate, this would mark a major expansion of the two companies’ partnership beyond AI chips and into vehicle connectivity.
The move signals Tesla’s growing focus on supply-chain diversification and next-generation communications as it prepares to scale its autonomous driving and Robotaxi operations.
Samsung’s 5G modem
As per industry sources cited by TheElec, Samsung’s System LSI division has completed development of a dedicated automotive-grade 5G modem for Tesla. The 5G modem is reportedly in its testing phase. Initial supply is expected to begin in the first half of this year, with the first deployments planned for Tesla’s Robotaxi fleet in Texas. A wider rollout to consumer vehicles is expected to follow.
Development of the modem began in early 2024 and it required a separate engineering process from Samsung’s smartphone modems. Automotive modems must meet stricter durability standards, including resistance to extreme temperatures and vibration, along with reliability over a service life exceeding 10 years. Samsung will handle chip design internally, while a partner company would reportedly manage module integration.
The deal represents the first time Samsung has supplied Tesla with a 5G vehicle modem. Tesla has historically relied on Qualcomm for automotive connectivity, but the new agreement suggests that the electric vehicle maker may be putting in some serious effort into diversifying its suppliers as connectivity becomes more critical to autonomous driving.
Deepening Tesla–Samsung ties
The modem supply builds on a rapidly expanding relationship between the two companies. Tesla previously selected Samsung’s foundry business to manufacture its next-generation AI6 chips, a deal valued at more than 22.7 trillion won and announced in mid-2025. Together, the AI chip and 5G modem agreements position Samsung as a key semiconductor partner for Tesla’s future vehicle platforms.
Industry observers have stated that the collaboration aligns with Tesla’s broader effort to reduce reliance on Chinese and Taiwanese suppliers. Geopolitical risk and long-term supply stability are believed to be driving the shift in no small part, particularly as Tesla prepares for large-scale Robotaxi deployment.
Stable, high-speed connectivity is essential for Tesla’s Full Self-Driving system, supporting real-time mapping, fleet management, and continuous software updates. By pairing in-vehicle AI computing with a new 5G modem supplier, Tesla appears to be tightening control over both its hardware stack and its global supply chain.
