Hmm Lets make the entire car a crumple zone...

If you look closely that was not a head on collision. It was a offset collision.
Im not sure what speed that was at but it makes a major difference.
Only the left half of the structure is absorbing the entire impact.
Many NHTSA tests are dont at 35mph but I cant say for sure on this one.
Either way the cabin didnt fold too bad. All that matters is the condition of the occupants. The vehicle can look like a crumpled piece of aluminum foil but it might have done its job by absorbing most of the crash energy.
