ON JUNE 21, 2020, ON A CITY STREET. MY WHITE BMW WAS TRAVELING WESTWARD AND A BLACK BMW WAS TRAVELING SOUTHBOUND. THE BLACK BMW RAN ITS RED LIGHT TO MY GREEN LIGHT. WHEN WE COLLIDED IN THE INTERSECTION THE COMPLETE FRONT END OF MY WHITE BMW IMPACTED THE BLACK BMW DRIVER'S SIDE, FROM APPROXIMATELY FROM THE FRONT TIRE, TO JUST INTO ITS REAR DOOR. THAT IMPACT CAUSED THE BLACK BMW'S SIDE AIRBAGS TO DEPLOY, AND EITHER AT THE SAME TIME OR UPON A SUBSEQUENT COLLISION WITH A BOLLARD, ITS FRONT AIRBAGS DEPLOYED ALSO. TO MY SHOCK AND DISMAY, NON OF THE AIRBAGS IN MY WHITE BMW DEPLOYED,. ALL AIRBAGS ARE STILL IN THEIR RESPECTIVE STORAGE COMPARTMENTS. ADDITIONALLY, I HAVE HIGHLIGHTED SEVERAL OTHER STANDARD SAFETY FEATURES OF THE CAR THAT DID NOT PERFORM ITS DESIGNATED FUNCTION EITHER. I WOULD LIKE YOU TO INVESTIGATE WHY THESE SYSTEMS FAILED ME. THANK YOU *TR
