In order to prove that you won't be able to take your eyes off of the new ŠKODA Fabia, the brand set up a fun attention test video. The ad is set up to show the car parked on a fairly ordinary street and features a man describing the best features of the car. While your eyes dart around to spot something sneaking into the frame, there are already changes sneakily being made.
At the end of the video, the changes are reverted, so you can see that you're not looking at the same street at all. The YouTube ad has done pretty well in terms of views, mostly because it cleverly offers up the kind of visual trickery that you'll want to replay over and over again.
