Probably not something that could be easily done, but maybe it will give someone an idea.
Tracked Aisle: A simple aisle-way with tracks for pushing/pulling around an in-vehicle cart. Tracked Aisles have no container space but take up the vehicle space reserved for containers. )To prevent container collisions) The carts which can be crafted onto a tracked aisle can only move on tracked aisle, attempting to pull them elsewhere results in collision same as pulling a cart into a wall or furniture.
Thoughts? Brainstorms off this idea?
