A vehicle collision detection system may be configured to coordinate with collision detection systems of other vehicles. The coordination may comprise sharing sensor data with other vehicles, receiving sensor information from other vehicles, using sensor information to generate a collision detection model, sharing the collision detection model with other vehicles, receiving a collision detection model from other vehicles, and the like. In some embodiments, vehicles may coordinate sensor operation to form a bistatic and/or multistatic sensor configuration, in which a detection signal generated at a first land vehicle is detected at a sensing system at a second land vehicle.
