1) the assistant was driving the car, XWL was the passenger
2) car lost control and hit the mid section of the highway which divides inbound and outbound traffic.
3) car spun out and finally pulled to a stop on the other side of the highway
4) XWL thought it was safe for her to get out of the car and she unbuckled her seat belt
5) this is when the truck rear ended them and this is why she had severe injury whereas the assistant still had her selt belt on and suffer minor injury.. NOTE*THIS IS A DOWN HILL HIGHWAY. (this is my assumptioni... "the trucker if loaded with stuff cannot pull to a complete stop even if it wasn't speeding. also this was 5 oclock in the morning...")
6) apparently all cars that get rear ended don't deploy front airbags. the only reason the two side airbags came out was because the assistant hit the car by the side on the mid section
7) passerby-ers tipped off the police that they saw the car going 120km/h--130km/h and pass them. but minutes later they saw the car stopped again on the right side of the road not moving. at that time the back of the car didn't show any sign of a crash. they later found out that the car sat XWL when they saw the news at home
