1. A method comprising:
collecting sensory data produced by an onboard sensor of an autonomous vehicle (AV) and sensory data produced by an onboard sensor of a secondary witness entity;
processing the collected sensory data to predict an imminent collision in an environment of the AV, the predicted imminent collision involving at least one participant entity;
providing an alert to the least one participant entity, wherein the alert is provided by the AV and prompts the at least one participant entity to perform at least one mitigating action with regard to the predicted imminent collision, and
wherein the AV and the secondary witness communicate with one another via a communications network using a standardized messaging protocol;
determining whether the at least one participant entity is a participant in the communications network if the participant entity is a participant in the communications network, providing the alert using the communications network; and
if the participant entity is a not participant in the communications network, providing the alert using an external collision imminent signal.
