so imagine a wagon had 4(i think is player limit on wagon at once) people on it but inside is empty so players mabye chould hide 1-2 other players inside (thay cant atk and takes time to get out (timer) and can look around but outsiders cant see there is player there (if driver looks he canssee hidden players, but riders and outside lookers cant tell) unless driver get off then all in open
or party permissions​ for wagon from driver and hidden players are just random stuff in cargo (so its not so suspicious)
kinda makes the wagon diver spot a must hold type of thing
