What Okinawa said. You want a structure that absorbs as much as possible of the energy. If it is turned into powder in the process, why would the occupants care?
Reminds me of a story told me by a GMH Engineer regarding second or third generation airbags shortly after they were introduced. They were getting complaints from Commodore drivers along the lines of:
”I had a minor accident and your @#$%# airbags went off and cost me $$$.”
GMH commissioned a University study of a representative sample of these accidents: the result? Each accident was life threatening - the system had worked so well the driver thought the accident was minor.
Sounds to me that Cirrus demonstrates good primary safety though I stand to be corrected.
