Some scientists have recently tried to optical camouflage technology so that one car Mercedes F-Cell can be almost invisible. Tarp that covered one side of the LED is coated. On the other hand there is a digital SLR (single lens reflex) with record function landscape covered car body. Technology pioneered by scientists at the University of Tokyo, Japan, the principle is the same with blue screen technology used during the event on television weather forecasts. Mercedes ad video shot in Hamburg highways and bridges in Bavaria, Germany. And the comments that appear to accompany the video on YouTube that range from fear there will be a collision because another driver did not see it. Another comment said that the advantage is that it can avoid tarp parking ticket.
