Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might be a recent change in the system. Has there been any software update or hardware modification in the past month?

Why it matters: Recent changes could directly impact system performance. Expected answer: Yes, a software update was deployed three weeks ago. Impact on approach: If confirmed, we'd focus on the update's impact on disengagements.

• Considering the metric itself, I'm curious about the definition of disengagements. Has the criteria for what constitutes a disengagement remained consistent?

Why it matters: Changes in measurement could artificially inflate the disengagement rate. Expected answer: The definition has remained unchanged. Impact on approach: If consistent, we'd focus on actual performance issues rather than measurement changes.

• Thinking about external factors, I wonder if there have been any significant changes in testing environments or routes. Have new areas or more challenging conditions been introduced recently?

Why it matters: Environmental changes could explain increased disengagements without indicating a system flaw. Expected answer: Some new urban routes were added to the testing program. Impact on approach: If confirmed, we'd analyze the impact of these new routes on overall performance.

• Considering user segments, I'm wondering if this increase is uniform across all vehicle types or concentrated in specific models. Can we break down the disengagement data by vehicle type?

Why it matters: Identifying patterns across vehicle types could pinpoint hardware-specific issues. Expected answer: The increase is more pronounced in newer vehicle models. Impact on approach: If true, we'd focus on compatibility issues with newer hardware configurations.
