Sounds like the Tractor Trailer violated traffic laws.
“Preliminary reports indicate the crash occurred when Baressi’s rig turned left in front of Brown’s Tesla at an intersection of a divided highway where there was no traffic light, the National Highway Traffic Safety Administration said. Brown died at the crash scene, which occurred May 7 in Williston, Florida, according to a Florida Highway Patrol report. The city is southwest of Gainesville.”
Looks like the Tesla had the right of way, and the Tractor Trailer Owner/Driver has every reason to attempt to discredit it.
That also could mean the tractor trailer was making a left hand turn (they turn really wide) and the driver was going too fast and because of watching the movie just didn’t see the truck to slow down and break.
This link better explains the accident and has a photo of the road.

Blame is going to come down to how fast the Tesla was going...the truck driver can only see as far as line of sight will allow him.
This accident happened in May...and Tesla gets real time data from all its autopilot enabled cars...so they know how fast he was going. Seeing as they haven’t blamed the truck driver, I’d say the safe bet is the Tesla was moving fast. We shall see.
Maybe America is different, but in Oz if the vehicle ahead is signalling a (right turn for us), the following vehicle is not supposed to overtake.
