Which of the following would not typically be a part of fleet performance metrics?

Customer service response time is not typically considered a direct fleet performance metric. Fleet performance metrics focus primarily on the operational aspects of the fleet, such as size, vehicle efficiency, and utilization. Total fleet size provides insight into the scale of operations, while vehicle condition reports are crucial for understanding maintenance needs and ensuring safety. Days earned percentage reflects the time vehicles are actively generating revenue as opposed to being idle.

In contrast, customer service response time is more related to the service levels provided to customers rather than the operational efficiency or performance of the fleet itself. It is an important metric in customer relations but does not directly measure how well the fleet is performing in terms of its operational goals.
