Too much crumple room. I don't see a lot of sense in having the vehicle crumple to absorb shock if it is going to keep on crumpling until you are squashed. I took the course in vehicle extractions & I always thought that it would be better if the part with the passengers was rigid. Then the front part could crumple & stop at the dashboard so as to avoid crumpling the people. I have had to take crumpled people to the hospital.
