Well it seems that Google has not bothered at all that this artist has taken a cart with 99 mobiles and used them to create fictitious traffic jams; that is to say, they do not exist.
Yesterday we already made known the artistic proposal of this man who simulated, thanks to those 99 connected mobiles, a nonexistent traffic jam. Dressed in a cart, he mounted those 99 mobiles to make Google Maps understand that there was traffic congestion.
Google's statements are these:
It is the same artist who has shared part of his experiment in German FAZ. Confirm that all the phones were equipped with their own SIM and that they were actively navigating, although he suspects that the experiment might as well have worked without delegating active navigation.
Although it does say that some movements have had to be carried out, since when the cart stopped completely, the streets appeared decongested. Like when a car passed the artist's cart, the congestion disappeared.
Un curious event that has surely served Google to improve Maps to fine-tune when collecting the data with which to later make up those traffic congestion that we see from the app.
