Tesla says 24/7 Robotaxi rides are a month away, riding on FSD v15

Updated 2026-09-16.

The Tesla Robotaxi is about to stop sleeping. Asked on X when the service would run around the clock, Tesla's VP of AI Ashok Elluswamy answered on September 4: "next month or so. the next tech to merge on the v15 plan will enable it." That puts 24-hour rides in October, in at least some of the cities where Robotaxi already operates.

The short reply carries two pieces of news. Robotaxi has been running on daytime and evening hours since it launched in Austin in June 2025, and going 24/7 is the difference between a demo and a transit service. And it confirms that FSD v15, the next major version of the driving software, is close enough to ship a module of it to the commercial fleet within weeks.

What we know about v15

Tesla said on its Q2 earnings call that some Robotaxi vehicles are already running early builds of FSD v15, and that v15 carries seven major architectural changes over the v14 stack, as Not a Tesla App reported. The company has not listed the seven publicly. Elluswamy has described the direction in broad strokes: a model that reasons further ahead, handles rare situations without hand-written rules, and needs less remote support per mile.

The 24/7 gate is telling. Overnight driving is not harder in the way a highway merge is harder. It is harder because the long tail gets longer: fewer cars around to give context, drunk pedestrians, construction crews that only work at night, and lighting conditions the daytime fleet never sees at volume. Saying that one specific module clears the way for round-the-clock service means Tesla has a concrete piece of the stack it considers the last blocker, rather than a vague confidence target.

Teslarati's coverage makes the same point from the rider's side: a robotaxi you can only hail during business hours competes with nothing, and a robotaxi at 3 AM competes with everything.

Where Robotaxi runs today

The fleet is a mix of retrofitted Model Ys and, since early September, the two-seat Cybercab. Austin is the original market. Dallas, Houston, the Bay Area and Miami followed, and Orlando and Tampa joined over the summer. Nevada has approved up to 5,000 vehicles for Las Vegas, which we covered when the state signed off.

Elluswamy did not say whether 24/7 lands in every city at once or Austin first. The pattern so far has been Austin first, everywhere else within weeks, so the safe reading is that October is the start rather than the finish.

When owners get v15

The part most owners care about is the consumer release. Tesla's stated target is FSD v15 on customer cars with the Hardware 4 computer late this year or early next. That follows the same shape as v14: the Robotaxi fleet runs the new version first, the rough edges get filed down with a safety monitor in the loop, and then it goes wide to Supervised customers.

Hardware 3 cars are not in that sentence. Tesla shipped a lighter v14 build for HW3 earlier this year, and there has been no v15 commitment for that computer yet. If you are on HW3, the honest expectation is that v15 arrives later and trimmed, if it arrives at all in that form.

A service, not a feature

What is quietly changing is the frame. For years FSD was a feature you bought for your own car. The 24/7 milestone belongs to a fleet business, where the metric is rides per day and the customer never touches a steering wheel. The consumer release is downstream of that now, which is a healthier order: the code that reaches your Model Y in December will have driven strangers around Austin all night for two months first.

It also means the cars people see most are the ones Tesla operates. A Robotaxi fleet that runs 24 hours a day is a rolling billboard for what a Tesla can do, and the Cybercab in particular gets looked at. Tesla has already used that to put its own designs on the road, with the USA 250 wraps on the Cybercab fleet.

Your own Tesla can do the same thing on its screen tonight. Open the studio, pick your model, and design something the car wears while it waits for v15.
