I saw the Dateline show last night. While I wouldn’t head out and try to sell my (hypothetical) F-150 tomorrow based on this, I don’t share Duck Duck Goose’s scorn for the whole study.
I have no cites for this (and I’m not sure just what sort I’d expect to find), but I was under the impression that the IIHS was generally fairly well-respected. Kind of surprising, I’ll grant, given who it’s funded by. It’s also certainly true that auto makers don’t hesitate to quote the IIHS’s test results when they’re favorable - a point made on the show.
Most of the analysis given on the show was focused on deformation of the truck cab. Now, I’d have preferred that some attention be given to the forces and loads suffered by the test dummy - which it was instrumented for - but I assumed that Dateline figured that its target audience wouldn’t be very interested in that and directed the focus of the interview elsewhere, to cooler and more eye-catching stuff.
That “elsewhere” would be deformation/crushing of the cab. While you could simply toss that off as being interested “only in damage”, I strongly disagree. I’m fairly confident that they were all totalled, so the body shop bill is pretty much inconsequential - even to the insurance company. The whole point was that in several of those trucks, the cab was deforming to the extent that the driver’s legs were being crushed - hardly irrelevant. The difference between the Tundra and the F-150 was considerable in that regard.
The quote of, “The forces recorded on the dummy’s head and neck in this crash were sufficient, that if a person experienced those forces, one possible outcome could be a fatal injury,” from O’Neill was, in my opinion, a carefully worded response to a loaded question. The on-camera reporter asked him (about the Ford test), “Is this a fatality?” I believe that a one-word answer - “yes” or “no” would have been inaccurate, and O’Neill was trying to get around that. The reporter would have loved to have landed some kind of “Ford Trucks Kill” soundbite, which O’Neill properly avoided giving. All O’Neill said was that the forces suffered by the dummy could kill - any statement stronger than that would have been pure BS. Some people would have survived such a crash, while others may not have.
The big question I have about all this is one of repeatability. All of this stuff is based on exactly one crash of each model in question. I doubt anybody thinks that the same model crashed ten times would produce precisely identical results, but some handle on the just how variable we could expect it to be would be reassuring. Perhaps the IIHS has done some studies and estimates on this - I don’t know.
I do appreciate that these tests are very expensive - on the show we watched $80-$90,000 worth of truck turned into scrap metal in very short order. That’s certainly motivation for only doing the tests once. And it would be justifiable if some kind of study had been done suggesting that the tests tend to be highly repeatable.
