“Endangered Species” is a rallying cry for car lovers worldwide and a visceral illustration of something many have come to realize -- the real world has become an unfriendly place for those who truly love automobiles. Economic concerns, environmental regulations, clogged motorways and a myriad of other restrictions all appear to threaten the very existence of the car enthusiast. Though the opportunities to have heart-racing experiences in the real world are becoming fewer and fewer, Forza Motorsport 4 offers a place to explore car passion freely without fear of speed traps or other impediments.
