feat(vehicles): 16 - a horse walks on legs in the game's physics (VehicleLegs): the package keeps its pace, stamina, hay and its refusal of water; the legs meet the ground, its steps and slopes and whatever is in the way, and what they cover along its heading is its speed, so a fence stops it and a trunk it glances pushes it aside. VehicleWorld.blocked is gone; the hire, hay and follow verbs move to keep.ludic
