A perfect one, sure, but in practice the car might, at best, treat it with less priority than a human in case of a difficult decision to make, and at worst, treat a « 40% confidence giraffe » as a false positive and ignore it
At the bottom of the « collections » page in the technology paragraph, they mention confusing the Yolo object detector into thinking you’re a giraffe with medium confidence instead of a person
This seems to prevent people from being detected by a generic object detector, but it doesn’t seem obvious that it will actually confuse a face detector… it might however confuse an autonomous vehicle, wouldn’t wear this in the street
