1998 BMW 3 Series Air Bags

AT APPROXIMATELY 4:45 P.M. CT ON FRIDAY, SEPTEMBER 30, 2016, I WAS DRIVING MY 1998 BMW M3 CONVERTIBLE HOME FROM WORK. I WAS ON STATE HIGHWAY 75 IN TULSA, OKLAHOMA, HEADING SOUTH. I DON'T HAVE A SPECIFIC RECOLLECTION OF MY SPEED AT THAT EXACT MOMENT, BUT WOULD ESTIMATE IT TO BE IN THE AREA OF 55-60 MILES AN HOUR, AS THERE WAS SOME TRAFFIC, BUT IT WAS NOT HEAVY. I WAS IN THE RIGHT-HAND LANE ON A PART OF THE HIGHWAY WHERE THERE IS NO CURB. I DID NOT SWERVE OFF THE SHOULDER. TULSA ROADS ARE NOTORIOUSLY BAD, BUT THIS PARTICULAR STRETCH OF HIGHWAY WAS REPAVED RELATIVELY RECENTLY. MY PASSENGER DOOR AIRBAG DEPLOYED SPONTANEOUSLY. I WAS NOT INVOLVED IN A COLLISION. I DID NOT HAVE A FLAT TIRE. BMW OF NORTH AMERICA HAS ASSURED ME THAT THE AIRBAG OPERATED APPROPRIATELY AND THERE MUST HAVE BEEN SOME STIMULUS TO CAUSE ITS DETONATION. I STRUGGLE TO ACCEPT THAT THERE WAS ANY STIMULUS AT THAT SPEED THAT WOULD CAUSE DETONATION OF JUST ONE AIRBAG WITHOUT CAUSING SOME DAMAGE TO THE VEHICLE.
