That test is not quite as advertised, as the two vehicles did not hit head on. They were offset almost two feet, favoring the driver's side, from the look of the video. IMO, that skews the data and the outcome of the test, and makes the claim of newer vehicles being safer invalid, as based on this test.
Also, I have never looked favorably on trashing old, antique vehicles of any kind just for publicity's sake. It just sticks in my craw when it's done to make a movie or TV show, or for something like this.
