Clarifying Questions (3 minutes)

Looking at the timing, I'm thinking there might be a seasonal component. Has this decrease coincided with any particular weather patterns or events?

Why it matters: Seasonal factors could significantly impact autonomous vehicle performance. Expected answer: Possible correlation with increased rainfall or extreme temperatures. Impact on approach: If confirmed, we'd need to focus on weather-related system improvements.

Considering user segments, I'm curious about the distribution of the decrease. Is this 15% drop uniform across all user groups, or are certain demographics more affected?

Why it matters: Identifying specific user segments could point to targeted issues. Expected answer: The decrease might be more pronounced in certain age groups or locations. Impact on approach: A skewed distribution would lead us to investigate user-specific factors.

Regarding recent changes, have there been any software updates or hardware modifications to the Zoox fleet in the past month?

Why it matters: Recent changes could be directly linked to the performance drop. Expected answer: Confirmation of a recent software update or hardware change. Impact on approach: If confirmed, we'd prioritize reviewing and potentially rolling back recent changes.

Thinking about the metric itself, has there been any change in how "successful pickups" are defined or measured?

Why it matters: Changes in measurement could explain the apparent decrease without actual performance issues. Expected answer: No recent changes to the definition or measurement process. Impact on approach: If changes are confirmed, we'd need to reassess the validity of the 15% decrease.
