I figured all you had to do was pull the dummy out of the crashed car, and slap it into another vehicle when the time came. Apparently, there is an entire process that the folks maintaining GM's 200 or so crash dummies for each accident.
It's also cool to see how small the electronics that record all the crash forces have become over the years. Check out the video below to see some of the stuff behind crash test dummies with GM.
