Researchers from Japan’s University of Keio have built a “see-through” Toyota Prius, that allows a driver to look through the rear seats and bodywork to see any obstructions behind, according to CNET.com.

The system is an application of previously developed optical-cloaking technology, which uses a camera mounted on the back of an object then projects that image onto its front, making it essentially invisible to anyone looking at it from that direction.
