Here's a really odd homebrew solution. The car is a new model not yet released. The problem is spies. Like paparazzi, they stalk the test race courses and suburbs around car design centers, hoping to score a photo of a brand new never-before-seen car to post on the car-fanatic web sites or magazines, like Winding Road, where this one was posted. To thwart the spies from capturing anything useful while they test the vehicle, the designers will cover it with... well... stuff. In this case, cardboard, duct tape, foam, plastic -- anything that was around the garage. I nominate it as a great case of rapid prototyping. No one yet knows what this vehicle is. Speculation runs toward it being either a Toyota or Subaru.
