Clarifying Questions (3 minutes)

• Looking at the timing, I'm thinking there might have been a recent software update. Has there been any significant changes to the autonomous driving system in the past two weeks?

Why it matters: Software updates can significantly impact autonomous vehicle performance. Expected answer: Yes, a minor update was pushed last week. Impact on approach: If confirmed, we'd focus on analyzing the update's impact on fleet performance.

• Considering the urban setting, I'm curious about any changes in traffic patterns. Have there been any major events or road works in London that could have affected the usual routes?

Why it matters: Urban mobility trials are highly sensitive to changes in the operating environment. Expected answer: There's ongoing construction in central London. Impact on approach: We'd need to assess how well the system adapts to dynamic urban environments.

• Given the nature of autonomous vehicles, I'm wondering about weather conditions. Has there been any unusual weather in London recently that might affect sensor performance?

Why it matters: Adverse weather can significantly impact autonomous vehicle sensors and decision-making. Expected answer: There was a period of heavy rain last week. Impact on approach: We'd investigate the system's performance in various weather conditions.

• Thinking about user behavior, has there been any change in the user demographic or usage patterns in the past week?

Why it matters: Changes in user behavior can directly impact fleet utilization rates. Expected answer: No significant changes noted in user demographics. Impact on approach: We'd focus more on technical and environmental factors if user behavior remains consistent.
