Wild animals regularly pose a threat to drivers. Here in Michigan, we worry about deer. In Colorado, the animals are a bit bigger (your author once saw a dead mountain lion on the side of the road outside of Telluride). Sweden, meanwhile, has to deal with moose. South Africa, though, trumps just about everywhere else, because occasionally drivers will need to contend with elephants.
Let's all collectively thank the glorious bit of technology that is Google Street View for letting the world know about the rare and mostly undocumented breakout of Elephantitis in Canada's deer population. Unlike the human form of the disease which is generally characterized by the swelling of a single body part, deer Elephantitis apparently morphs the hapless affected creatures into real-life elephants. If you're driving in the area, extra caution is advisable.
