What is the time scale for increasing the bounty vs how long it takes to charge a scooter?
If we give the 'hoarders' the benefit of the doubt, could it be the bounty is increasing while they have a bunch of scooters queued up to charge? They grabbed 20 in their truck, and it takes 5 hours to charge 1, but they only have 2 outlets, but the bounty goes up every 12 hours, so they have a backlog?
