To be fair, no one but Elon knew whether he would go through with it or pull the plug at the last minute...and maybe even he didn't know given how mercurial he is.Criminal investigation and having DOJ involved seems very far fetched to me. The NTSB should be involved in looking at the accidents, of course. Do you think Boeing or Airbus will be put on trial after the next aircraft crash involving one of their airplanes? How about the airlines? The FAA came down hard on Boeing after the 737 Max issues and subsequent NTSB investigation, but no criminal charges were filed.
This comes the day before Elon officially owns Twitter. Coincidence?
