I read the entire thread and couldn't find a single reference to what these settings would be, just a lot of hand-waving and "I haven't isolated them". Seems like an extreme jump to conclusions.
But, let's imagine there is such code - what kind of optimization could actually be done, that would meaningfully improve the tests? The car is on a sled, at a predefined speed. All that can be changed is maybe the timing of airbags or the collision sensor sensitivity, and if there was an ideal set of parameters that improves safety results, I can't imagine that is not the one used in the real world. Am I lacking imagination?
