Don't pick up hitch hikers* and/or, if you break down, don't accept help from Brendan Murdoch look-a-likes. You my find you get a few miles down the road, then he skins you and wears you as a costume.
* A poster on here can no doubt tell you a story how his bleeding heart made him pick up a traditional owner who was hitching a ride to "town camp". They got to conversating and the hitcher forgot that he needed to ask the driver to stop, as he needed to urinate due to the copious amounts of goon he consumed. He then proceeded to urinate in the drivers car. Hilarity ensued.
