I was traveling approx. 50 mph and a woman pulled out in front of me and i (t boned ) her. my chest hit the steering wheel and then the air bag deployed immediately all functions stopped working.the car filled with white smoke from the air bag. my windows were up and i could not roll them down nor steer.i could not breath the car was rolling it stopped at approx. 50 ft.when i got out i was gasping i had a white substance all over me in my nose. i'm very concerned.
