Tesla AI lead says 24-hour Robotaxi service

Tesla AI lead Ashok Elluswamy said on September 4, 2026, that 24-hour Robotaxi service could begin in 'the next month or so.' He made the comment on X, replying to a rider who wanted overnight Cybercab trips. The capability hinges on a new software module merging into the Full Self-Driving v15 development plan.

Elluswamy's statement provides the clearest near-term timeline yet for overnight unsupervised operation. Tesla's paid Robotaxi network currently runs from 6 a.m. to 10 p.m. daily across six cities: Austin, Dallas, Houston, Miami, Orlando, and Tampa. This 16-hour window is shorter than the 6 a.m. to 2 a.m. schedule the company used for much of the prior year.

The Tesla AI lead did not specify which vehicles would get the update first. He did not say whether the change would apply to the purpose-built Cybercabs, the existing Model Y fleet, or both. He also offered no city-by-city rollout list.

The v15 Software Foundation

The link to Full Self-Driving v15 is significant. Tesla has described v15 as a step-change architecture with seven parallel improvement tracks and roughly ten times more parameters than earlier builds. Early versions of that software already operate on the Robotaxi fleet and contain about 40 percent of the planned gains.

By July 2026, the unsupervised fleet had logged more than 380,000 miles across six cities in two states. Tesla said the vehicles maintained an impeccable safety record with no notable incidents caused by the vehicles themselves. The company has repeatedly argued that camera-based end-to-end neural networks, rather than extra sensors, are the core of the solution.

Operational and Economic Impact

Overnight service would test that claim in lower-light conditions. It would also raise vehicle utilization, a key variable for Robotaxi unit economics. The company has already begun using public Superchargers at night and is building dedicated Robotaxi charging sites.

Riders have asked why software must change if the cars already drive in the dark. The practical answer appears to be reliability and scale. Tesla has held back mass expansion until more of the v15 stack is merged. The company cited the need for higher confidence before putting thousands of unoccupied vehicles on streets around the clock.

If the next module arrives on the timetable Elluswamy sketched, 24-hour service could begin in October 2026 in at least some markets. That would mark a shift from a daytime-bounded pilot to a service that can run whenever demand exists, including the late-night hours that have so far remained out of reach.

Regulatory Scrutiny and Expansion

The news follows Tesla's launch of public Cybercab rides in Austin on September 3, 2026. That launch caught the attention of the National Highway Traffic Safety Administration (NHTSA). The agency opened an Audit Query into the Cybercab's Federal Motor Vehicle Safety Standards certification. NHTSA stated it needs more information, particularly because the vehicles lack permanently attached, conventional manual controls like a steering wheel and pedals.

Tesla has added 45 Cybercab units to its fleet of Robotaxi-enabled cars in Austin, according to public documents. Concurrently, Tesla Asia announced the Cybercab will be on display this month in Hong Kong, Tokyo, Beijing, and Shanghai.
