To promote their revolutionary car that produces 0.0 emissions, Mercedes-Benz sent a vehicle a cruising around the streets which it deemed the 'Invisible Mercedes.' Spectators were baffled when they saw what appeared to be a see-through car causally driving by.
To create the Invisible Mercedes, the car was covered in LED lights. Then a camera from the other side of the car sends its images to the LED lights so it appears as if the vehicle is transparent. While one can tell that the car isn't actually transparent, it's still quite perplexing on the eyes.
The Invisible Mercedes turned out to be a great marketing move, because it made everyone's heads turn (despite the fact that it was invisible). Sadly, one cannot buy the car with the invisible feature because that would cause way too many accidents.
