Final answer:
The estimated societal cost of aggressive driving over the last ten years is $24 billion, covering medical expenses, property damage, and lost work time.
Step-by-step explanation:
The estimated cost of aggressive driving to society over the last ten years is $24 billion. This estimate takes into account the expenses associated with medical costs, property damage, and lost time from work due to aggressive driving-related incidents.
Using the provided example, we can understand how insurance companies might calculate premiums based on the risks and damages associated with car accidents for a group of 100 drivers. The total damage incurred by such accidents would be $186,000, illustrating how risk is spread over a larger pool to calculate individual premiums like the $1,860 mentioned in the example. However, this is a separate scenario and does not influence the estimated societal costs of aggressive driving, which is $24 billion.
