Only the state can formally accuse you of a crime. The complaint accuses Uber of a variety of torts under a variety of theories, and includes accusations necessary to seek punitive damages ("The conduct of the Defendants and each of them was engaged in with fraud, oppression and/or malice, and was in conscious disregard of the rights and safety of others ...").

There is significant overlap between the elements and standards necessary to warrant punitive damages and criminal negligence statues, but they aren't identical and the two processes are entirely separate in terms of how and whether they proceed.
