Here's a thought:
in order for the police department to headoff a liability suit by the production company and stunt driver the cops press charges against the driver. Charges like not yeilding to an emergency viehicle, assualt of a police officer in the performance of his duty, use of deadly force to increase the assualt charge. This way if you can get the driver to plead to the lesser charge with a fine and no jail time then it would be hard for him to file in civil court.
