Although I believe it, I am always approach a "study" like this that is produced by a tire company and propagated by a tire retailer.
It's probably true, but the last part showing a car going through boxes means that the marketing department was absolutely involved in this "test". I can't see a regular engineer setting up a visual aid like that when numbers are typically more important to them then a crashing visual aid. At least they didn't stand up a family of crash dummies posed to be walking across the street. That would be too obvious.
Always the cynic...
