In a quirky twist in the world of autonomous vehicles, an Arizona eBike enthusiast and content creator, Jason B Carr, has stumbled upon a peculiar way to prompt Waymo’s self-driving cars to stop: wearing a simple t-shirt emblazoned with a stop sign.
Carr’s unconventional experiment, captured in a series of videos, showcases his ability to halt Waymo’s Jaguar I-Paces by strategically revealing his stop sign-adorned t-shirt. While some skeptics speculated that the vehicle may have mistaken Carr for a pedestrian entering the road, subsequent tests from a sidewalk confirmed that the t-shirt alone was sufficient to trigger the autonomous vehicle’s stop mechanism.

Undeterred, Carr conducted further tests at night to assess the vehicle’s response under different conditions. The results were varied, with the vehicle stopping in some instances but not in others. Carr attributes this inconsistency to his t-shirt’s lack of reflectivity compared to a real stop sign, suggesting that the artificial nature of his makeshift stop sign may have influenced the vehicle’s decision-making process.
Despite the light-hearted nature of Carr’s experiment, it sheds light on the complexities of autonomous vehicle technology, particularly in navigating unexpected scenarios, or “edge cases.” Carr himself speculates that the vehicle may have mistaken him for a construction worker holding a stop sign, a theory that, while unconfirmed by Waymo, underscores the nuanced challenges of designing autonomous systems to interpret and respond to a wide range of real-world situations.
Waymo has yet to respond to requests for comment on Carr’s experiments. However, this light-hearted yet insightful test serves as a reminder of the intricate challenges inherent in developing autonomous vehicles capable of safely navigating the complexities of the real world.
