MY DAUGHTER WAS DRIVING WITH A PASSENGER IN THE FRONT, ON A TOWN STREET AND A VEHICLE PULLED OUT IN FRONT OF HER. THE IMPACT WAS ON HER FRONT BUMPER AND HOOD PUSHING THE SIDE QUARTER PANELS BACK. THE OTHER VEHICLE WAS AN OLDER PONTIAC GRAND PRIS, THEIR AIRBAGS DEPLOYED. NO AIRBAGS DEPLOYED ON THE TOYOTA PRIUS.WHY DID THE AIRBAGS NOT DEPLOY?
