BMW warned that "Slow Cameras" would soon be installed on British roads to photograph drivers going more than 20 mph below the speed limit, but they had a solution:
After months of experimentation, BMW engineers have devised a solution to avoid detection — ZIP (Zoom Impression Pixels). ZIP is a pixel-based coating that covers the entire exterior of the car. If you are travelling below the speed limit in range of a Slow Camera, sensors around the car detect the camera and the pixels immediately become blurred. This gives the impression of higher velocity and the Slow Camera is fooled into thinking the car is travelling at the correct speed.
BMW's Head of Mandate Avoidance, Hans Uphoo-Gotit, reassured consumers that ZIP technology would have no effect on normal speed cameras.
