You may have seen it pass by: the video of a Tesla Optimus robot sitting at the wheel of a car, on a road presented as being in Korea. Short and clear answer: there is no robot in this video. It is a South Korean Tesla fan in an Optimus costume. The verification by Fact Crescendo, published on 14 August 2026, already concerned the circulation of this sequence and settled it with one word: fake. That did not stop it from resurfacing five days later.

And the best part is that no one lied at the start.

Where does this video come from?

The original sequence dates from 28 February 2026. It was published on X by the account @emzipori2, with a caption in Korean that frankly admits the joke. It reads: “Tesla Optimus robot learning to drive on the roads of Korea! Can we call that a real robotaxi, right?”, all punctuated with laughing emojis. The robotaxi, in Tesla’s vocabulary, is the driverless car — we come back to that below. It was a gag, signed as such.

On 19 August 2026, another account, @HumanSapiensX — with just over three hundred followers — reposts the video. Without the caption. Without the emojis. Without the joke. And there, according to the count noted by El País on 19 August, the repost nearly reaches 200,000 views, while the original post, the one that was joking, tops out at 103,800 views.

That is the real mechanism, and it applies to many other subjects: the prank is not the problem. The copy-paste that removes the joke, that is.

The three details that betrayed the costume

The most useful thing in this story is not the verdict, it is the way to get there. Here are the clues noted by El País on 24 August 2026 — and you can do the same check on any video of the same kind.

  • The size. The official specifications of the Tesla Optimus give 1.73 metres for 57 kilograms. The filmed silhouette appeared taller and more voluminous.
  • The gaze. The silhouette was looking at the camera at times. To see a very human reflex in that is our reading: a machine busy with its task has no reason to do so.
  • The ease. The supposed robot was driving with an ease that Optimus has never publicly demonstrated, writes El País.

Three details, three simple questions: does the silhouette match the official dimensions? Does the machine behave like a machine? And above all: has it ever done this in public, anywhere other than in that specific video?

Robotaxi and Optimus, it is not the same thing

In our view, it is this confusion that made the video credible. At Tesla, these are two distinct programmes. In the company’s nomenclature, the robotaxi refers to a car driving with the Full Self-Driving system (fully autonomous driving), presented as having no human driver — this is the in-house classification, not autonomy observed by a third party. Optimus, for its part, is categorised among the “bots”, the physical mobile robots. And no public document from Tesla describes an Optimus driving a car on open roads.

Put differently: a car supposed to drive itself has no need to have a humanoid installed behind the wheel. The two ideas resemble each other in the imagination, they do not meet anywhere in the company’s documents.

Where is Optimus really at?

Here too, there is solid ground to report on. According to a regulatory filing by Tesla dated January 2026 and cited by the fact-checkers, the Optimus Gen 3 is the first version designed for mass production. The preparation of the first production line was then in progress, and the start of production was announced before the end of 2026.

That is the documented state of affairs, as of January 2026: an assembly line being set up, not a robot passing its driving test.

Our obsession, and why it matters here

Usually, when we watch a robot demonstration, our vigilance focuses on one specific point: does the machine decide, or is a human operator piloting it remotely? We call that teleoperation, and it is the first thing we try to establish here. A teleoperated robot is not an autonomous robot, even when the video is spectacular.

This time, we went even further down the rabbit hole: there was neither an autonomous robot nor a teleoperated one. There was no robot at all. Just a fan, a costume, and a good joke that lost its caption along the way.

The method, to keep up your sleeve

Three reflexes, and they can be done from your phone. One: trace back to the original post, because it is often that one which contains the key — here, a mocking caption and laughing emojis. Two: compare what you see to the official characteristics of the model, size and weight foremost. Three: ask yourself if the machine has ever shown that gesture elsewhere, in front of witnesses.

If the answer is no, the video is not proof. It is just a video. And sometimes, as here, it is even very funny — provided you watch it with its original caption.
