Sci-fi doesn't just describe our imagined future - unlike almost any other form of storytelling, it actually helps to build it. Going all the way back to Jules Verne and the Nautilus, science fiction has been beta testing our best and worst ideas, and futuristic movie cars are prime example of that.True, futuristic cars from movies are usually as much about style as substance, and pretty much anything in a film reflects the standards, ideas, and fears of the time. But movies, being a mainline into pop culture, are part of the big cyclical machine of imagination and creation. Also, some of them are just freaking AWESOME. Vote your favorite from our varied visions of tomorrow, from high-tech Wonderland to Hellish post-apocalyptic dystopia.
