“ON AUG 16, 2018 @ 6:30 AM WHILE EXITING AT THE GARAGE IN MY APT HEADING TO WORK; I STARTED THE ENGINE OF MY CAR AND IT WAS OKEY. I STARTED TO DRIVE ON THE RAMP ON THE DRIVE WAY THE ENGINE STOPS. I REVERSED/ BACK UP AND STARTED THE ENGINE AGAIN, WHILE ON THE RAMP AGAIN IT ACCELERATED AND NEVER STOP THOUGH BRAKE WAS APPLIED. THE CAR WON'T STOP; SO I DECIDED TO CRASHED MY CAR AT THE CAR PARK ON THE SIDE STREET, BEFORE I REACH TO THE TRAFFIC LANE AND MIGHT CAUSE A FATAL ACCIDENT. I DAMAGED MY CAR ON THE DRIVER SIDE AS WELL AS THE CAR I CRASHED ON/ THE BUMPER, HEADLIGHT & FENDER WERE VISIBLY DAMAGED.”
