A Tesla Cybercab was forced to brake hard repeatedly when a man jumped in front of the autonomous vehicle, according to a video circulating on social media. The footage shows the man hiding behind a lamppost before leaping into the path of the robotaxi as it approaches, causing the vehicle to stop abruptly. He repeats the prank when the Cybercab picks up speed, forcing a second emergency stop. The vehicle's reaction time appears to be excellent, but the incident highlights the challenge autonomous cars face in dealing with unpredictable human behaviour.
The Cybercab is Tesla's purpose-built robotaxi, which was rolled out on a limited scale in Austin, Texas, earlier this month. The vehicle has no steering wheel, no accelerator pedal, no brake pedal and no mirrors. Tesla says the Cybercab complies with all Federal Motor Vehicle Safety Standards, but the National Highway Traffic Safety Administration (NHTSA), the US equivalent of the DVLA, is investigating whether that claim holds up. The agency has questioned how a vehicle without conventional controls can meet standards designed around human drivers.
The video also shows a driver in a blue Jeep witnessing the scene and overtaking the stationary Cybercab. While the prank appears to be an isolated act, it raises broader questions about how autonomous vehicles should respond to deliberate interference. Tesla has not commented on the incident, and it is not clear whether the man was identified or faced any consequences.
The NHTSA investigation is ongoing. The agency has previously taken a cautious approach to autonomous vehicle deployments, requiring manufacturers to demonstrate that their systems can handle edge cases, including pedestrians behaving erratically. Tesla's rollout in Austin is one of the first commercial deployments of a fully driverless taxi service without a safety driver on board. The company has positioned the Cybercab as a key part of its future business, but regulatory scrutiny could slow its expansion.
For now, the Cybercab continues to operate in Austin, where it is available to a limited group of users. The incident with the man jumping in front of it is unlikely to halt the programme, but it adds to the growing body of evidence that autonomous vehicles must be prepared for the full range of human behaviour, from the careless to the deliberately disruptive.
