An enthusiast from the United States discovered that a T-shirt with a Stop sign can stop self-driving taxis on the road in most attempts (judging by the video, three out of four times). Waymo's robotic vehicle system treats a person standing on the side of the road with a large Stop sign on their chest as a traffic sign.

User jasonbcarr explained that one time the taxi did not notice his sign on his chest, it was dark on the road and there were no reflective elements on the T-shirt. In other cases, various self-driving taxis were paused while the user stood on the side of the road with a stop sign on the front of his T-shirt. The enthusiast asked not to use this magic trick for evil.

Experts explained to the media that Jasonbcarr raised the issue of the safety of unmanned taxis. And it is also unclear what would have happened if, instead of a stop sign, a person had a T-shirt with a speed limit sign, which would allow driving in the city in violation of the rules, which could lead to an accident or abnormal operation of the taxi autopilot.

Previously, anti-drone activists in San Francisco discovered that placing a traffic cone on the hood of a car paralyzes the operation of Waymo and Cruise cars. Self-driving taxis cannot continue driving and do not take new orders until taxi service employees or passers-by remove the cone from the hood.

In July 2021, Tesla electric car owner Jordan Nelson said that Tesla's FSD (Full Self-Driving) autopilot navigation system sometimes mistakes the moon for a yellow traffic light and begins to slow down the car.

In 2020, Tesla owners discovered another bug. After updating the Autopilot program to control traffic lights and stop signs, the electric vehicle could confuse Burger King signs with stop signs. Tesla has since fixed a bug in the navigation software.
