We used to joke that a drone mesh network to a local Starbucks was the best opsec.
Even better-- do a cron job for the requests you want to make on the end-point phone.
Glue that to a car, turn it on, and take off.
After a long enough time that the battery has died, ride your skateboard up to retrieve your anon filez.
Hahah, awesome idea. In the past I wanted to stick phones to the trees in the random forest and made my own onion mobile phone network. But cars are better because moving all the time.
When I think about it, rental e-scooters would be probably even better.
These scooters already have modems on them. Hah, hacking them to be a mesh network (although I guess not many have WiFi/Bluetooth), sounds like a plot device for some "hacker" movie.
