There is a golden rule: "Don't mess with anybody who rides around in a chariot made entirely of human bones." This can be applied to real life as well as fantasy games, though it must be noted that apart from one member of the Infinite Interactive art department who swears he once saw one after a night out at a local bar, we have never actually encountered such a strange vehicle in real life. Still, if we did, we think it would probably be a good rule to abide by.
