Are there any US federal or state laws stipulating some sort of black box style recording of data for accident investigation?

If not then I suspect a Tesla will turn out to be quite surprisingly forgetful about what it was up to in a road traffic collision.

RTC is a UK term that took over from RTA (road traffic accident) - it describes what happened rather than heading off into the weeds as to cause.

I don’t know about laws, but Teslas automatically record and save everything in the event of a collision. My brother was hit by another car while driving a Tesla a few years ago and it was very easy to retrieve video from the Tesla’s cameras and show who was at fault.
