I disagree. People need to know that autopilot doesn't eliminate their responsibility for safely driving the vehicle and paying attention. People need to know they HAVE to respect the autopilot warnings. If that is happening too much in an area and so is too cumbersome, then don't use autopilot. And to wait a year for that to be released would not be in the public interest. Neither would a year of unanswered BS from short interests and competitors, considering that Tesla's vehicles overall are incredibly safe.
I think NTSB's action to remove Tesla is fine. Tesla felt they had to release such information (and there's a good argument for that, IMHO), but that is against NTSB's policy as it could compromise the investigation. So be it. Removing them may be best for all.
