I think this is giving the NTSB too little credit. Remember, the people who work at the NTSB deal with statistics all day, and for the most part genuinely care about reducing traffic deaths. So I think that, for their part, it'll look more like the way they've handled investigations into crashes with current partial automation (ie Tesla's autopilot): with a lot of emphasis on the overall effect of the system on accident rates, rather than on one specific crash.
