It is pretty clear from the video that the car driver, probably an african american overweight woman talking on her cell phone, did not stay in her lane when the highway turned right thus slamming (or coming close) to the semi, backing out to the right and overcorrecting which caused the sedan to hit the front cab of the semi.
Since the road turned right on her without any warning, she things it is a right wing spiracy with a violation of her fifth dimensional rights.
