When was the last time you used Google Maps? You know, when you prowl around and look at those Red Traffic Jams in in overlay and are like ha, suckers.
Well, turns out you can hack google maps to make an artificial traffic jam, which makes Google Maps redirect people away from the area.
Simon Weckert did just that. He picked up 99 second hand phones, chucked 'em in a little red wagon, and went for a walk down empty streets. Google, being too clever saw 99 devices moving slowly down the street and imediately thought it was a jam, so changed the overlay to red, and starts redirecting traffic around the 'blockage'
