This was the actual reason if I recall correctly. He lived on a small side street that suddenly had lots of traffic. He realized Google maps was suggesting that street for directions and came up with this ingenious plan to get Google to redirect traffic elsewhere.
Kinda the opposite, really. This guy is literally causing the pests (rats, not children) of the modern city to avoid him, not be attracted to him and follow him out of town to The Children's Crusade.
I assume Google detects if you're walking with your phone, so that walking people don't mess up the traffic jam feature. And that dolley tricks these phones into thinking they're in a car.
I'll take a wild guess that he maybe wanted to build distance between himself and the phones, especially if he does this repeatedly.
For a few phones, radiation and tissue heating is not an important consideration but for 100 phones it might be.
Is this illegal at all or is there a follow up? I don't care personally, I think it's pretty funny, but feds typically don't like this type of thing. Curious what Google responded with
