Final answer:
16-year-old drivers and those over 82 have high rates of mistakes due to the developmental state of their brains and neurodegeneration, respectively, affecting decision-making and risk assessment in driving.
Step-by-step explanation:
16-year-old drivers are cited for more mistakes than any other age group except for drivers over 82 because of their lack of experience and the still-developing state of their brains. Young drivers' brains are still maturing, especially in the areas responsible for decision-making and risk assessment. On the other hand, drivers over the age of 82 often exhibit a decline in cognitive functions due to the neurodegeneration that comes with age. This can affect their reaction times, situational awareness, and overall driving abilities. While teenage drivers may have quicker reflexes than older drivers, their risk-taking behaviors are higher due to their developmental stage, leading to a higher incidence of mistakes and accidents.
