How far until a lie?

“Dramatization. Underbody digitally modified.”
That’s the fine print underneath the latest Ford pickup ad. You’ve probably seen it – two bulldozers tackle a Ford pickup, one on the front, one on the back. They crush it, showing the engine and bed collapsing while the cab stays intact. Then a buzzer sounds and some nice folks in lab coats open the doors and get out of the totally safe pickup.
Except it’s digitally modified and labeled a dramatization. At what point does a modification of a safety feature demonstration cross into negligence?
