Yesterday I was stopped at a red light on a highway and a Tesla Model S rear ended me at high speed, twice! There were two impacts somehow. It was a 4-car pileup and my car was destroyed.The driver said she was using Autopilot, that an OTA update had had a problem earlier in the day, and that she had actually had the same kind of collision on Autopilot previously!I talked with the NTSB who said that they won't investigate because no one was killed.I talked with the NHTSA who said that they can't take a complaint: only the driver can file a complaint and they will only investigate if they "see a trend".This seems like a serious issue that someone should be looking at. Does anyone have any idea about how to get this actually investigated to see if it was another Autopilot failure?
