Rotarian John Daily combined has 25 years of law enforcement, two degrees in mechanical engineering, and years of teaching traffic accident investigation to create a fascinating program of film and discussion of vehicle crashes between trucks, buses, and automobiles.  He presented pictures of various staged crashes where the vehicles were equipped with instruments (and crash dummies) that measure the effects of the impacts.  The big take away is not to be involved in vehicle crashes, wear your seatbelt, and watch out for the other guy while you drive responsibly
