To clarify, I was responding to the OP with regard to the "investigation" part. Authorities won't launch an investigation on someone rear-ending someone else on the basis that "autopilot did it". As a wronged individual he should make sure that he is properly compensated as non-responsible for the crash. The driver herself can (and maybe should!) at least contact Tesla to inquire about the whole thing. If truly Teslas with FSD are causing more accidents than another car then yes at some point some government body will investigate but they won't care about a single incident with only material damages.
