The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

On its first day carrying passengers in Gothenburg, Sweden, an autonomous bus operated by Västtrafik was rear-ended by a tram after braking near Kapellplatsen. No injuries were reported, but the incident caused property damage and service disruption, highlighting risks in deploying AI-driven public transport systems.[AI generated]

Why's our monitor labelling this an incident or hazard?

The autonomous bus is an AI system as it performs autonomous navigation and decision-making. The collision with the tramway is a direct consequence of the AI system's operation, constituting harm to property and potential risk to passenger safety. Although no injuries occurred, the incident itself is a realized harm event involving an AI system. Hence, it meets the criteria for an AI Incident rather than a hazard or complementary information.[AI generated]

Why's our monitor labelling this an incident or hazard?
The self-driving bus crash involved an AI system (autonomous driving AI) directly causing a collision with a tram, which is a physical incident involving harm to property and potential risk to passengers. The presence of a driver onboard does not negate the AI system's role in the incident. Similarly, the Waymo robotaxis' failures to avoid flooded areas and illegal passing of stopped school buses are malfunctions or operational failures of AI systems that have led to safety risks and operational disruptions. These are direct harms or risks caused by AI system malfunctions or inadequate development. Hence, both events qualify as AI Incidents under the framework, as the AI systems' use and malfunction have directly or indirectly led to harms or safety risks.
