1. A system, comprising:
one or more processors;
a memory communicably coupled to the one or more processors and storing:
a control module including instructions that when executed by the one or more processors cause the one or more processors to in response to determining that a physical connection between a vehicle and a trailer has disconnected with no remaining physical connection therebetween, determine trajectory information for navigating the trailer without a connection to the vehicle and activate a mobility component to facilitate movement of the trailer;
communicate the trajectory information from the vehicle to the trailer to cause the trailer to follow a trajectory associated with the vehicle, including instructions for following the vehicle without the physical connection; and
monitor whether the trailer is following the trajectory, including: responsive to determining the trailer is not following the trajectory associated with the vehicle, communicating following information to cause the trailer to follow a second vehicle that was previously not associated with the vehicle and the trailer.
