Roof Crush Summit
Really good article on roof crush. It starts off taking you through one of the "lucky" survivors of roof crush, a paraplegic named David Garcia. Then they walk you through FMVSS 216. The article reminds of a film I've seen from GM (I think, could've been Ford) from about 1960 or so. It shows an onboard camera view of a rollover in a sedan. The vehicle stays together pretty well and everyone who sees the video says the same thing: "even the roof held." It is pretty scary that we say that, but everyone does. Problem is roof crush is an all too often issue in vehicle crashes, especially rollovers. Please read the whole article carefully, some life saving information in there.
