Coby Persin is a “YouTube personality” who specialises in “pranks” and “social experiments,” meaning that he makes his living inconveniencing and intruding upon the lives of ordinary people who are just trying to get through the day. Recently, he visited New York City, and naturally, that meant blocking a lane of Seventh Avenue traffic to pose for the camera in front of his six-figure-price tag BMW i8. One New Yorker was having none of it though.
