Either there wasn't enough visibility for the Semi driver to see that there was a car that would hit him when he tried to turn across two lanes of highway -- which means the speed limit there is too high -- or he saw the oncoming car and figured it would stop regardless of right-of-way -- which wouldn't surprise me at all the way some people are a-holes and people with bigger vehicles think they can drive however they want (Buses using 2 lanes, etc).OMG, that intersection is a deathtrap looking for victims in the first place. At freeway speeds I can totally see people turning left across the 2 lanes and misjudging how much room they have. And the Tesla driver, if the car was self driving they wouldn't give you a steering wheel and pedals.
