Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be seasonal factors at play. Has there been any significant change in weather patterns or road conditions in the past month?

Why it matters: Seasonal changes can impact truck operations and route efficiency. Expected answer: Minimal weather changes, but we'll need to verify. Impact on approach: If confirmed, we'd focus more on internal factors.

• Considering the metric specificity, I'm curious about the calculation method. Has there been any recent change in how miles driven per day is measured or reported?

Why it matters: Ensures we're comparing apples to apples in our analysis. Expected answer: No changes in measurement methodology. Impact on approach: If changed, we'd need to reassess the validity of the 15% decrease.

• Given the autonomous nature of the fleet, I'm wondering about recent software updates. Have there been any significant updates to the autonomous driving system in the last 1-2 months?

Why it matters: Software changes could directly impact driving patterns and efficiency. Expected answer: A minor update was rolled out three weeks ago. Impact on approach: If confirmed, we'd prioritize investigating the impact of this update.

• Thinking about fleet management, has there been any change in the number of trucks in operation or their deployment strategy?

Why it matters: Changes in fleet size or deployment could affect overall miles driven. Expected answer: Fleet size has remained constant, but we'll need to check deployment strategies. Impact on approach: If deployment has changed, we'd focus on optimizing route planning and truck utilization.
