1. A system of an ego vehicle comprising:
a vehicle control system;
a non-transitory memory; and
an onboard unit communicatively coupled to the non-transitory memory and the vehicle control system, wherein the non-transitory memory stores computer readable code that is operable, when executed by the onboard unit, to cause the onboard unit to execute steps including:
sensing a remote vehicle to generate sensor data describing the remote vehicle and driving behavior of the remote vehicle;
classifying a type of the remote vehicle based on the sensor data;
retrieving a behavior profile for the type of the remote vehicle that identifies criteria for the type of the remote vehicle and classifications of abnormal driving behavior and normal driving behavior based on the criteria, wherein classifications of normality are variable based on the type of the remote vehicle;
comparing the driving behavior of the remote vehicle to the behavior profile for the type of the remote vehicle;
determining that the driving behavior of the remote vehicle is abnormal based on the comparing and a driving maneuver to execute to eliminate an origin of the abnormal driving behavior, wherein the ego vehicle is autonomous; and
autonomously executing, by the vehicle control system of the ego vehicle, the driving maneuver to eliminate the origin of the abnormal driving behavior.
