It appears that Fiat managed to find out exactly when the Google Street-View car was going to be driving past the Volkswagen Group Sverige AB headquarters in Sweden. What they did with this knowlege was park a 500 right up on VW's steps in front of the door.
If you look around, you can see the red fiat trailing the Google street-view car, so this appears to have been a pre-meditated prank. We love it.
Next time Fiat should make sure to have a bikini clad Catrinel Menghia as well.
