Sounds like you are running across Birds that were moved and when the mover tried to capture they were denied. As a result they just leave the scooter where they moved it to. These must come back on the map at some point. I'm not sure when though.
Move them when they are in rider mode and not on the charger map.
Are you being serious? The second you open the app regardless of whether you are using rider mode or not it starts tracking your location. You've even given the app permission to have location access which is used to find Birds near you and track the progress of your ride. You could, however, enter airplane mode before coming in contact with the Birds.
