How to create a traffic jam with 99 smartphones

A Berlin-based artist decided to test the accuracy of Google maps and devised a novel method to check how good are Google maps when it comes to computing traffic on the roads. Simon Weckert got 99 second-hand smartphones and put them in a hand cart. He switched on the GPS navigation on Google maps in all phones. He proceeded to walk around with the cart on the streets of Berlin including the local Google office as well. Since Google maps was switched on in all the phones, it is assumed that the Google server must have picked up the movement of 99 smartphones moving slowly at one place. This is almost akin to having a lot of people driving cars with their Google maps on during peak traffic hours. The Google algorithm soon changed the status of these streets from normal to heavy congestion with red lines wherever Simon went with his cart. Google maps started showing red lines on streets which were as good as empty. While this may not be a common occurrence, but this feature can clearly create problems. It can be misused by anti-social elements to cause fake traffic jams and divert traffic which may help criminals. Clearly, Google needs a little more tweaking to its maps feature to make it more real-time.
