Are you sure that's a smart? Looks like it may have more than 3 lugs. I doubt another car would have fared much better. You've got two trucks with a lot of mass (solid structure to support them) and one in the middle with very little (relatively). Any car is going to be crushed before either truck crushes some or the dump truck in front is pushed forward.
My friend bought a mini cooper last year and I immediately called it a death mobile. He then said that it's safe and has a lot of airbags. I told him all the air bags won't do anything when the body of the car is crushed into the passengers. I think he realized I was likely right.
Anyways, I went looking for the story of the accident in this picture and unfortunately came across a smart (that was actually a vw fox) head on collision with a semi on accident. Absolutely gross. Body torn in half. I'm done searching.
