They see me rollin’, they hatin’
This could actually be implemented quite easily - we already have 30 gallon barrels - make them into a vehicle part thaty can be mounted on a wheeled light frame and voilla ! One rollable garbage can ready.
The regular kind, as in the thick metal sheet ones ? These could also be rolled - flip them on the side, fill them with scrap metal and weld the lid shut rolled, for example. Such a non-steam roller could be an extremely mean weapon to be pushed in front of you (is this possible in terms of game mechanics ?) and an even meaner one when mounted on a vehicle.
In my facility-spout topic, I’ve thought about doing such a thing with the press rolls from a paper mill, but a garbage can filled with heavy stuff could do the trick as well.
Back to the topic:
Light posts might not be that difficult, depending on how the game handles road junctions. Also: road/rail junctions !
