Air Bag Not Deploy problems of the 2008 Mini Cooper S

I was in a bad car accident in which my car was rear ended. I was in the very most right hand lane on the highway, at a stop in stop and go traffic. The vehicle behind me did not stop, hitting me at approximately 75 mph. As a result, my car spun out to the right and hit the guard rail on the side of the highway head on. The car then bounced off of the guard rail, and spun about 180 degrees to the left, where the rear end of the car then hit the same guard rail and finally stopped. When the car crashed into the guard rail head on, the air bag did not deploy and I hit my head and my chest against the steering wheel. I sustained a fracture in my t2 vertebrae and bad chest bruising.

The seat occupancy sensor malfunctions. The passenger side airbag may not deploy even if the passenger side seat is occupied. The airbag light sometimes stays on, while sometimes goes away. Mini has recalled several cars for seat occupancy sensor mat fault but my car isn't on the list. The light stays on when vehicle is stationary and also while running. I'm unable to use the passenger seat for safety concern. The airbag light goes away on its own as well but turns back on within a few miles.
