Which animals could survive car crashes that would be fatal to humans?

This.

A group of Australians built a model of what it would be like if humans were somehow designed to survive car crashes. Obviously, this is a ridiculous model, but designed from the ground up.

The brain has more ligaments to help sustain itself during an impact. The legs are actually digitgrade rather than plantigrade, so he would be actually walking on his toes like cats and dogs. These allow him to jump out of the way in a spring-loaded fashion. The ribcage is also extraordinarily thick, acting as an airbag to cushion the chest should he suddenly lurch forward if he was not wearing seatbelt.

While a person like this would never actually exist in nature, it’s still an interesting concept when it comes to bioengineering things to be safer.
