The point you are missing is the landowner/Farmer is probably being threatened with prosecution by his local authority for storing scrap vehicles, deemed as waste, leaking oil and pollutents, on his agricultral land without a waste licence, and not complying with the criteria for storage of waste, ie, on a concrete base with oil and pollutent drain traps, The farmer is held resposible for clearing up his land. Gone will be the days when old vehicles are found on farms, this also applies to having a derilect or dismantled vehicle in your own garden/driveway if the council declare it as waste
