Abstract: A system and method of providing dynamic vehicle navigation information to a follower vehicle based on a leader vehicle location of a leader vehicle. The method includes: establishing a communication link between a first personal mobile device and a second personal mobile device; after establishing the communication link, obtaining leader vehicle identification information and follower vehicle identification information, wherein the leader vehicle identification information is used to identify a vehicle as the leader vehicle, and wherein the and follower vehicle identification information is used to identify a vehicle as the follower vehicle; periodically obtaining the leader vehicle location of the leader vehicle; and causing a follower vehicle device to be periodically provided dynamic vehicle navigation information based on the leader vehicle location, wherein the dynamic vehicle navigation information includes directions so that the follower vehicle at least partially follows the leader vehicle.

Abstract: In an example, a system is disclosed. The system includes an event classification module that is configured to determine whether a vehicle event is an emergency event or a non-emergency event based on vehicle sensor data. The system also includes a determination module that is configured to determine a driving mode of a vehicle at the time of the vehicle event in response to a determination that the vehicle event is the emergency event. The determination module is configured to determine the driving mode by comparing a driving mode timestamp to an emergency timestamp corresponding to the vehicle event.
