Abstract: Various embodiments provide methods, vehicle computing devices, storage media, and systems for briefly providing PathHistory information in Broadcast Safety Messages (BSMs) sent from a vehicle when PathHistory information is not required to be included in all BSMs. Various embodiments may include broadcasting BSMs including PathHistory information during a period of time following a change of the vehicle's pseudonym certificate and broadcasting BSMs without PathHistory information at all other times. Some embodiments may further include determining whether sufficient path history points are available for PathHistory information generation, accumulating path history points in response to determining that sufficient path history points are not available for PathHistory information generation, and broadcasting BSMs including PathHistory information during the period of time once sufficient path history points have been accumulated.
