Here is a great training idea from a fellow vehicle rescue instructor in Germany.  It has some great ideas for training...

The Moditech Crash Recovery System ("CRS") is a valuable tool for rescuers that are called to perform vehicle extrication of trapped occupants at vehicle accidents. It allows rescuers to gather technical information about the vehicle in a short period of time. Using the CRS as part of the size-up of the vehicle, for example to identify cut versus non-cut areas, the overall safety to the rescue operation can be increased while the extrication time can be shortened.

However, it is not easy to practice the use of the Crash Recovery System during training, primarily because there is a lack of late-model vehicles to train on. Usually vehicles for training are older, junk vehicles from the scrap yard that do not provide a real technological challenge, as compared to vehicles manufactured today.
