detecting, by a service executed in the system, an accident involving a first vehicle, wherein the detecting is based on an accident indication received by the service over a network from a second vehicle not involved in the accident, the second vehicle different from the first vehicle, and wherein the accident indication from the second vehicle is responsive to messages received by the second vehicle from other vehicles, the messages received by the second vehicle from the other vehicles comprising temporary anonymized identifiers of the other vehicles;
in response to the detecting of the accident, verifying, by the service, that the accident occurred by sending queries to a roadside unit and a third vehicle, and receiving responses to the queries from the roadside unit and the third vehicle, the responses containing event data collected by the roadside unit and the third vehicle of events in a vicinity of the accident;
in response to the detecting of the accident, collecting, at the system, the event data and further event data relating to the accident from the second vehicle; and
reconstructing, by the service, a scene of the accident based on the event data and the further event data from the second vehicle, wherein the event data and the further event data from the second vehicle comprise temporary anonymized identifiers of the second vehicle and the third vehicle.
