Which is what he was talking about
It would not be necessary to take the cars off, it would just look ridiculous, plus, as TFM said, nobody likes an empty ferry
In most missions with Red
Eagle (its not called Red Funnel),you start the mission by leaving the port, therefore it has been loaded. It would be kinda stupid to have the vessel empty, it would be pointless, doing a crossing, and not letting anybody off the vessel, don't you think?
