Good question. I'm not based in the US, so I don't know the ins and outs of federal or state level investigations.

In the UK I think the data is released to the coroner (assuming a fatality) but I'd have to research that to be sure.

I'm not in the US either, and my knowledge of the matter is largely from Mayday or Air Crash Investigations which runs on the National Geographic terrestrial TV channel here. But I would expect that this Uber case will get a somewhat similar treatment as airline crash investigations.
