WHILE DRIVING ON I-75 IN FLORIDA COMING FROM KENTUCKY (RELOCATING MY MOTHER IN LAW), I AND A FRIEND WHO WAS TAKING A TURN DRIVING SMELLED AN ODOR SIMILAR TO SULFUR OR NATURAL GAS. WITHIN 10-15 MINUTES, SMOKE STARTED COMING OUT OF THE FRONT DRIVER ENGINE COMPARTMENT. DRIVER IMMEDIATELY PULLED TO THE EMERGENCY LANE AS A FIREBALL EXPLODED FROM THE SAME AREA AS THE SMOKE. WE BOTH DOVE OUT OF THE VEHICLE ON THE PASSENGER SIDE. THE ENTIRE VEHICLE WITH NEARLY ALL THE CONTENTS BURNED, ALL THE WAY DOWN TO THE TIRES. *TR
