how many tries does it take opus 5.5 to save a crash-test driver?...

we gave it a deadly car: an open buggy, no belt, no airbag. at 56 km/h into a wall the dummy flies out. 29 broken bones.
opus adds parts, crashes the car, reads the injuries and tries again
everything here was built by opus 5.5: the car, the 79-bone dummy, the crash physics, the x-ray renderer and the 7 tries.
time: 8h 16m
cost: $27
