We live in a dynamic world with rapid changes. A good example is the car manufacturers who are constantly striving to increase safety features in their future car models. The enhanced safety features makes us more inclined to drive fast and risky. High speed in combination with heavy vehicle, use of strong material and advanced technology in the car structure leads to severe accidents with the outcome of an extremely complicated rescue operation.
