Two things here
"Tesla refused to cooperate with the probe." really are they allowed to do that? US justice seems a little toothless.
Autopilot, given this is the US, surely someone should be suing Tesla for misappropriation of a term, their solution, at best, is advanced cruise control, it most certainly isn't an Autopilot as installed in Aircraft, though I suspect some slimy lawyer would argue the case given the more limited requirements of that device. At the very least Tesla should be sued for over inflation of capabilities.
It does remind me of the story of the person making a cup of tea after activating cruise control in their RV, unsurprisingly it didn't end well. This was mostly urban myth but did actually happen in the UK in 2018 https://www.suffolkgazette.com/news/motorhome-crash/
