That last part is mainly because the weight/size that your cockpit takes up on the plane/boat/train/truck could be used for other goods that pay that much for the space, plus a little extra for giving you the privilege of course, a bit of fuel costs, but mainly, these shipments are happening anyways whether your cockpit/wheel is on it or not so its competition between companies that can charge whatever they want because someone somewhere will need **** delivered.
"That last part" was irony and sarcasm; rhetoric meant to show the inanity of this thread, eh.
