I WAS DRIVING IN A RURAL AREA WHEN ALL OF A SUDDEN I HEARD WHAT SOUNDED LIKE AN EXPLOSION. MY FIRST INSTINCT WAS THAT I HAD BLOWN A TIRE BECAUSE IT WAS SO LOUD. HOWEVER, THE CAR WAS HANDLING FINE AND NO WARNING MESSAGES CAME ON. MY HUSBAND AND I BOTH SAID "WHAT WAS THAT?" EVERYTHING ON SEEMED FINE MECHANICALLY SO WE KEPT DRIVING, BUT A BIT SHAKEN BY THE SUDDEN LOUD NOISE. I FEW HOURS LATER WE STOPPED FOR GAS. AS MY HUSBAND WENT TO CLEAN THE WINDSHIELD HE NOTICED THE SHATTER OF THE GLASS ROOF PANEL. WE THOUGHT BACK TO THE INCIDENT EARLIER AND REALIZED THAT MUST HAVE BEEN THE SOUND ME HEARD.
