The hoarder finds some value in hoarding. In extreme cases of hoarding where you find the house is filled with items often the value comes from the hoarder not having to worry about inadequate supplies. A person who hoards food because of previous issues with having adequate food is sating their need for security. This isn't an extreme case but the same reasons still exist, hoarding the scooters is providing value. Take efforts to reduce value. Like start letting the scooters talk to each other and you'll be able to find the cycle in the graph where the hoarded scooters only talk to each other until one pays outs handsomely and it joins the rest of the public scooters. Or make a scooter pay out less if it has been idle for an extended period of time even with low battery value. Or the opposite, make a scooter pay out more if it's getting higher than average use.
