The present disclosure relates to a method performed by a scenario reconstruction system (1) for supporting assessment of unforeseen driving scenarios of a host vehicle (2). The scenario reconstruction system stores (1001) continuously and/or intermittently timestamped sensor data (3) comprising the host vehicle's geographical position and surroundings captured with support from one or more surrounding detecting sensors (22) onboard the host vehicle. The scenario reconstruction system further detects (1002) at a scenario time instance, involvement of the host vehicle in an unforeseen driving scenario, potentially involving one or more other objects (4). Moreover, the scenario reconstruction system derives (1003) from the timestamped sensor data, subsets (30) of sensor data, e.g. snapshots, pertinent plural separate timestamps prior - and potentially at and/or subsequent - the scenario time instance. The scenario reconstruction system further identifies (1004) one or more surrounding detecting sensors-provided entities (5) respectively present in the subsets pertinent at least two respective separate timestamps. Moreover, the scenario reconstruction system selects (1005) at least a first entity (6) out of the identified entities, fulfilling selection criteria. The scenario reconstruction system further communicates (1006) to the at least first selected entity, request data (8) prompting the at least first selected entity to provide stored timestamped sensor data (63) of its surroundings.The disclosure also relates to a scenario reconstruction system in accordance with the foregoing, an arrangement - e.g. a vehicle and/or cloud server - comprising such a scenario reconstruction system, and a respective corresponding computer program product and non-volatile computer readable storage medium.
