I PULLED INTO A CHICK-FIL-A DRIVE THRU. THIS FAST FOOD CHAIN HAS EMPLOYEES OUTSIDE THAT COME TO YOUR CAR AND TAKE YOUR ORDER. THE GUY THAT CAME TO ME ASKED ME IF SOMETHING WAS WRONG WITH MY CAR. HE SAID IT SOUNDS LIKE THE ENGINE IS RACING. I DIDN'T RECOGNIZE IT UNTIL HE MENTIONED IT. WHILE I WAS SITTING IN THE LINE WAITING TO PICK UP MY FOOD, I NOTICED THE ENGINE WASN'T RACING AS BAD AS IT HAD BEEN. WHILE I WAS SITTING IN THE DRIVE THRU LINE, THE CAR ACCELERATED AND TOOK OFF. I LOST CONTROL OF THE CAR. I HIT ANOTHER CAR AS THE CAR LEFT THE PARKING LOT AND RAN INTO THEIR FENCE. THE FENCE WAS THERE FOR SAFETY MEASURES, TO KEEP YOU FROM GOING DOWN AN EMBANKMENT. THERE ISN'T A POLICE REPORT. THE POLICE DIDN'T COME BECAUSE IT WAS PRIVATE PROPERTY I CAN PROVIDE INFORMATION, (IF REQUESTED) FROM MY INSURANCE COMPANY. THEY DECLARED THE CAR TOTALED ON 4/9/2021.
