Claim 18:
19. The method of claim 17, wherein each of the inter vehicle LIDAR systems comprises a respective plurality of lasers, the method further comprising for each of the intra vehicle LIDAR systems and the inter vehicle LIDAR systems:
performing, by each LIDAR system, operations including:
receiving, during a passive state, a passive return comprising one or more first optical returns from one or more optical sources other than the plurality of lasers;
receiving, during an active state, an active return comprising one or more second optical returns corresponding to a laser firing of at least one laser of the each LIDAR system and one or more third optical returns from the other optical sources;
comparing a passive electrical signal generated based on the passive return and an active electrical signal generated based on the active return; and
based on the comparing of the passive electrical signal and the active electrical signal, removing, from the active electrical signal, at least a portion of interference corresponding to the one or more third optical returns from the other optical sources.
