To me AI in law seems better since you have a judge at the end. If you get something wrong it'll most likely be fine. There seems to be some tolerance for mistakes when representing yourself so it's most likely helpful for small claims and fighting tickets/fines. In a perfect world people wouldn't be paying BS fines or letting people scam them because they can't be arsed to take 2-3 days to deal with it the first time (once you've done the spiel once it's much easier).
