Just to clear things up. i did not take this video but i do know the truck driver. the vid was given to him i assume by the people in the car. Apart from very shaken the young lady driving the car was unhurt. this is a bloody big truck and when you sit in the cab you can only see about 10 feet ahead. the truck driver is a very good one and has years of experience and about the last person in the world to suffer from road rage. just didn't feel a thing. And yes its real !!

he was fully loaded at the time with 30000kgs in the tank. running at about 44000kgs gross weight
