Final answer:
Driver error accounts for approximately 54 percent of all fatal auto accidents. This is exemplified by a study where 14 out of 30 fatal accidents were due to driver error,
Step-by-step explanation:
The question asks which percentage of all collisions is caused by driver error. The given data suggests a frequency of driver error in auto accidents. From the information provided, it can be deduced that driver error accounts for a significant proportion of auto collisions.
It is stated that approximately 54 percent of all fatal auto accidents are caused by driver error, according to research by the American Automobile Association.
This finding is further examined in a study of 30 fatal accidents, out of which 14 were found to be caused by driver error. This lends credibility to the AAA's statistic, implying that driver error is indeed a common cause of accidents.
In terms of real-world impact, understanding and reducing driver error could be crucial for improving safety on the roads and lowering insurance costs.
This is highlighted in the example of dividing 100 drivers into groups according to the risks and associated costs of their accidents, leading to a total estimated damage cost of $186,000 for the group.
The question is asking us to determine the percentage of collisions that are caused by driver error. To solve this problem, we need to analyze the information given in the reference.
According to the American Automobile Association, driver error is listed as the cause of approximately 54% of all fatal auto accidents. However, we are not given any information about the proportion of all collisions that are caused by driver error. Therefore, we cannot accurately determine the answer to the question based on the information provided.
