A resident of the German capital, Simon Weckert, clearly demonstrated the unreliability of Google Maps, a service popular with motorists. Moving along the streets of Berlin with a cart loaded with 99 smartphones, Weckert was able to create an artificial jam on a completely empty street.
Analyzing the number of simultaneously incoming signals and the pedestrian speed of their movement, Google decided that the smartphones moving in the cart belong to the drivers stuck in the traffic jam and painted this section of the road in red. Accordingly, drivers who saw information about the congestion changed their routes.
The German did not disclose the details of the experiment. For example, it remained a mystery whether SIM cards were installed in the phones, and whether the navigator worked on all smartphones. The experimenter did not answer the questions under the video, the authors of which wondered why Google does not accept buses for traffic jams, whose passengers often use smartphones during the trip.
