A guy carted 99 phones around to create traffic jams on Google Maps

He discovered that if the wagon stopped moving, Maps would not show a traffic jam, so the wagon had to consistently be in motion for a jam to get registered.
Additionally, if a vehicle drove by the wagon at a normal speed, Maps would also register traffic as normal. It was only when the wagon was in motion and the street was empty that a traffic jam would show on Google Maps.
Google had this to say in response to the “hack” to register false traffic jams:
"Whether via car or cart or camel, we love seeing creative uses of Google Maps as it helps us make maps work better over time."
