Michael's grandfather was teaching Michael how to drive a car. At first, Michael was frustrated because his grandfather's reactions and driving were rather slow; his grandfather explained that while he's not as fast as he used to be, he is more careful in his driving in later life. When Michael followed his grandfather's example and avoided hitting another car due to his cautious driving, he appreciated his grandfather's slow, but careful driving. This difference in ability involving the loss of speed but gain of caution best illustrates Baltes' principle that development is:
