Imagine what it would be like if, in the near future, we were able to take all the crash test dummies out of all the cars in all crash test labs around the world, because we no longer needed them. Imagine how quick, inexpensive, and accurate crash testing would become if we could marry the mathematical data representing all the adult male, adult female, and child vehicle occupants, and run all the crash tests as simulations. If you can imagine this scenario, you can imagine that all future cars will be capable of providing individualized restraints based on information of each occupant instead of affording safety only for a handful of anthropomorphic test devices (ATDs), also known as crash dummies.
