In the commercials, drivers and their passengers get into accidents while driving the VW Jetta; upon exiting the vehicle unharmed but shaken, the characters exclaim "Holy..." (as in the beginning of the expression "Holy shit") before being cut off by a titlecard that jokingly finishes their sentence with the word 'safe' instead of 'shit', and then adds 'happens' (a minced version of 'Shit happens', as stated above).
