Speculating: IR interference might have jammed this vehicle's LIDAR for an instant as it sampled the vicinity of the hazard. Any power in the passband of the detector might have been sufficient to saturate it and make it less sensitive to the returning LIDAR signal. This could come from another LIDAR unit in the vicinity. Other possible jammers might include IR laser pointers, TV remotes, or IR camera illuminators.
