Wow the van actually seems to be built like a tank, the crumple zones appear to be crack zones with a little compression. it appears the VW t3 was traveling at 80 + mph when it pancaked into the wall and considerably slower in the crash tests Chrstophr posted. the truth is somewhere between the two examples I would guess.
I believe the smart cars needs a new design / materials to increase the survivability of its users when a accident occurs. It would be a great little car to try out new materials and configurations with.
