This Reddit thread has a good explanation: https://www.reddit.com/r/SelfDrivingCars/comments/sac1ti/waymo_suing_california_dmv_to_prevent_release_of/ https://www.reddit.com/r/SelfDrivingCars/comments/sac1ti/way... TLDR: DMV asked for proprietary details during permit process to which Waymo complied noting they were trade secret. A third party used California's FOIA to see Waymo's application in full, so the DMV asked Waymo to provide redacted copies. The third party has challenged redactions, so DMV told Waymo the only way to prevent them from releasing it is to sue to the agency.
