Elon Musk missed his deadline for deploying unsupervised Full Self-Driving technology in Tesla vehicles by the end of 2025, marking another delay in the company's autonomy push. Tesla failed to launch a robotaxi service available without human supervision to over 50% of the US population, as Musk had promised. Instead, limited employee tests occurred in Austin in early 2026, according to The Verge. Musk now cites a need for 10 billion miles of driving data, up from the over 7 billion miles Tesla has accumulated.
Pattern of Broken Promises
Musk has repeatedly shifted timelines for Full Self-Driving, or FSD, over the years. He promised robotaxis in 2019 and driverless operations in 2021, but those targets slipped. In 2025, Musk assured investors that unsupervised FSD would roll out broadly by year's end, including a robotaxi network covering much of the US. That did not happen. The Verge reports only supervised tests with employees in Austin and San Francisco, using kill switches for safety.
Current FSD operates at Level 2, requiring constant driver attention. Tesla tracks over 7 billion miles of FSD data on its website, but Musk recently said 10 billion miles are necessary for safe unsupervised use. This pivot came just days ago, per The Verge. Analysts on YouTube noted the shortfall as an indirect admission of delay.
- Tesla deliveries fell in 2025: 418,227 vehicles in Q4, down 16% year-over-year.
- Full-year total reached 1,636,129 vehicles, a 9% drop amid competition from BYD.
- NHTSA extended Tesla's response deadline to February 23, 2026, for a probe into 8,313 FSD incident records; Tesla processes 300 records per day.
Electrek reported Chinese regulators rejected Musk's claim of FSD approval in February 2026, calling it "not true." This followed a late 2025 promise of an early 2026 rollout, despite a 2024 mapping partnership with Baidu. State media in China dismissed the timeline.
Regulatory and Operational Gaps
Tesla faces mounting scrutiny from regulators. The NHTSA probe examines FSD compliance with traffic laws, with Interesting Engineering noting the extension coincides with Tesla shifting FSD to subscription-only after February 14, 2026. No outright sales will occur post that date.
In China, progress stalled despite Musk's Beijing visit in 2024. Electrek highlighted the denial as a setback, with regulators stating the timeline misaligns with rules. Tesla had touted approval as imminent.
Operationally, Tesla disbanded its Dojo supercomputer team, per Bloomberg reports shared on Reddit. This raises questions about AI compute for FSD, potentially increasing reliance on Musk's xAI venture. Current robotaxi efforts remain supervised, far from the promised scale.
Business Insider quoted Morningstar analyst Seth Goldstein: "I think 2026 is going to be the prove-it year for Tesla's robotaxi business... That's ultimately going to be the major driver for Tesla this year."
Stakes in a Cooling EV Market
Delays in FSD erode investor trust, contributing to stock declines. Reddit threads from investors cite a 35% drop from peak levels, linking it to FSD failures and Musk's distractions with X, SpaceX, and politics. High-credibility sources like The Verge, Electrek, and Business Insider agree on the pattern of unmet promises.
The broader EV market cools, with US tax credits expired and BYD gaining ground in China and Europe. Tesla's lineup feels stale, per Business Insider, risking a third straight year of sales declines in 2026. Autonomy remains central to Tesla's valuation as an AI play, not just a carmaker.
The Verge captured the irony: "Last year, Tesla defied its critics by boldly launching a robotaxi service that, by the end of the year, required no human supervision and was available to over 50 percent of the US population. At least that’s what Tesla CEO Elon Musk told us would happen by the end of 2025. The reality, of course, was much different."
Musk remains optimistic. On the Q3 2025 earnings call, he said Tesla's Cybercab, a purpose-built autonomous vehicle without steering wheel or pedals, would enter volume production in April 2026. He added: "I think the demand will be pretty nutty."
What's Next for Tesla Autonomy
Tesla plans Cybercab production in April 2026 and a Roadster demo later in the year. Musk hinted at "something special" involving Optimus humanoid robots. Analysts warn these hinge on scaling autonomy.
The NHTSA probe response due February 23 could bring fines or restrictions. In China, regulatory timelines remain unclear, with no confirmed next steps after the recent denial.
Data accumulation continues, with Tesla at over 7 billion miles. Free trials might accelerate this, but reaching 10 billion depends on fleet growth. Reddit users report frustration, with some early adopters noting persistent FSD glitches in complex scenarios.
Battery Wire's Take
These endless FSD delays aren't just slip-ups—they're a core flaw in Tesla's strategy. Musk's habit of overpromising erodes credibility, and pinning everything on a 10-billion-mile threshold feels like another excuse to buy time. We see real risk here: if Cybercab production flops in April without true unsupervised tech, Tesla faces investor exodus and deeper sales slumps. Skeptics are right to question whether Musk's divided focus on politics and other ventures is tanking the company's edge in autonomy. This isn't hype; it's a house of cards waiting to collapse unless Tesla delivers hard proof by mid-2026.
