Barley a week after Elon Musk clashed with Waymo on social media over who has the superior self-driving technology, Tesla Inc. has entered a pivotal phase of testing its long‑promised robotaxi service. Public sightings this weekend captured a Tesla Model Y outfitted as a “Robotaxi” and operating on city streets without a safety driver or any occupant in the front seats. Musk reportedly confirmed that unsupervised tests are now underway, marking what supporters see as a breakthrough and critics worry could be a premature leap in autonomous vehicle deployment.
Locals in Austin recorded video footage showing a specially marked Model Y gliding through traffic with its steering wheel actively navigating intersections despite having no one in the driver’s seat or the passenger seat. Musk posted on the social platform X that “testing is underway with no occupant in the car,” indicating that Tesla feels confident enough in its latest Full Self‑Driving (FSD) software build to remove human safety monitors from certain test vehicles.
A Milestone or a Risky Step?

Tesla’s robotaxi vision stretches back years, including grandiose forecasts during its 2019 “Autonomy Day” when Musk predicted a future of widespread driverless ride‑hailing vehicles. Since then the company has faced repeated delays in delivering truly unsupervised autonomy. Earlier in 2025, Tesla began piloting a robotaxi service in Austin and the Bay Area that still required human monitors inside the vehicle to take control in challenging situations.
This weekend’s sightings represent a marked shift because, for the first time, at least one Tesla robotaxi—Model Y SUV—was observed without any human safety monitor behind the wheel or in the passenger seat. Industry trackers note that, while this step technically meets Musk’s repeated end‑of‑year timeline to remove safety drivers from parts of the Austin fleet, it is still early and limited in scope.
Tesla’s own internal goals remain ambitious. Musk has publicly stated that Tesla plans to scale the Austin robotaxi fleet significantly by late December and eliminate safety monitors in large parts of the city as 2025 closes. Company leaders have described the unsupervised tests as preliminary and not yet involving paying customers.
Regulatory and Safety Questions
The regulatory backdrop is complex. In contrast to California and some other states where autonomous testing rules require a licensed driver in the vehicle, Texas regulations have allowed Tesla more latitude to experiment with robotaxi operations without a driver physically present. Nationwide, regulators have shown heightened scrutiny of autonomous systems following high‑profile incidents involving other companies’ self‑driving vehicles. For example, Waymo’s autonomous cars were recently caught illegally passing stopped school buses.
The incidents, reported in Texas and Atlanta, prompted federal investigation and a recall of over 3,000 vehicles. Faulty software allowed cars to ignore flashing red lights and extended stop arms. These incidents prompted calls for deeper data transparency and stricter oversight of autonomous tests on public roads.
Despite this milestone, Tesla has not publicly released detailed, independently verified data demonstrating that its FSD system is measurably safer than human drivers. This lack of granular safety statistics stands in sharp contrast to the reporting practices of rivals such as Alphabet’s Waymo, which publishes disengagement reports and safety metrics tied to regulated testing programs. Removing a safety monitor without robust safety proof may increase risks for pedestrians and other road users.
Market Reaction and Public Debate
Tesla’s stock has shown some positive movement around the recent announcements, reflecting investor enthusiasm for autonomous mobility’s potential to transform ride‑hailing and mobility economics. However, analysts remain cautious. While some see the unsupervised tests as a technological breakthrough, others question whether Tesla is using public testing as a proxy for rigorous validation, given the absence of transparent data on real‑world performance.
In online forums and social platforms, reactions range from excitement about a future dominated by robotaxis to concerns about safety and skepticism about whether this particular phase truly represents Level 4 autonomous driving. Many commenters emphasize that a handful of unsupervised test runs does not equate to readiness for commercial deployment to paying passengers.
