We met some guys in San Diego who ran a (definitely illegal) business doing this with scooters. They wanted to sell us one of them for $200 (against market price of $6-700); we declined.
Basically, around about 2016 (maybe?) the number of electric scooters in San Diego exploded. We had like 6 different companies dumping them by the pallet load, I guess as an availability tactic.
I imagine what they were doing was taking them off the road and into someplace where they looked accessible on the GPS but couldn't actually be accessed, depleting the battery by winding them down, and then deconstructing them enough to get them into Tijuana, where they would be stripped and the brain of the scooter replaced. Apparently, they had a guy in TJ who could basically "de-GPS" the scooters. Then, they would ship them back up and sell them cheaply.
