What's the formula for KE? What's the dominant term in that equation? What's the exponent on that term? Anyone telling you that energy absorbing structures are of significant value except at a very narrow range of speeds and impact type is peddling falsehood. The bulk of the improvement since the 90s (well into the era of crumple zones, remember they are a prerequisite for airbags) has been from better airbags, side curtain airbags, pre-tensioners and better modeling software that allows those things as well as seats and seatbelts to be engineered to levels that were unheard of even a decade ago. Whether you hit hard objects in a crash has a lot less to do with luck these days. Stronger cabins are a plus (especially for non-frontal crashes) too.
