2011 Honda Insight POWER TRAIN,AIR BAGS,VEHICLE SPEED CONTROL

THIS MORNING (AUG 6, 2016), MYSELF AND MY DAD MET WITH AN ACCIDENT AND WAS DRIVING HONDA INSIGHT 2011 LX MODEL. NOTE THAT MY DAD WAS SITTING IN THE FRONT PASSENGER SEAT. LET ME DESCRIBE THE ACCIDENT. I WAS ABOUT TO PARK MY CAR IN FRONT OF SPROUTS GROCERY STORE IN THE PARKING AVAILABLE SPOT JUST FACING SPROUTS. SO YOU CAN IMAGINE THAT I WAS ABOUT TO PARK MY CAR AND THE SPEED WAS AROUND 5MPH. ALL OF A SUDDEN, I COULD FEEL MY INSIGHT ENGINE EXPERIENCING SUDDEN ACCELERATION AUTOMATICALLY AND THEN I WAS TRYING TO APPLY THE LEG BRAKE TO MAKE SURE IT DOESN'T SPEED UP. SUDDENLY, THE INSIGHT STARTED SPEEDING UP AND DIDN'T STOP EVEN AFTER SLAMMING ON THE BRAKE AND IT JUMPED ON THE PARKING CURB AND FINALLY HIT THE CONCRETE PILLAR IN FRONT OF SPROUTS RESULTING IN DEPLOYING THE DRIVER AIR-BAG AND THE PASSENGER AIR-BAGS. MY WINDSHIELD DEVELOPED A DEEP CRACK AND I BELIEVE MY CAR IS GOING TO BE TOTALLED. WITH THAT, IT DIDN'T STOP, AFTER HITTING SO HARD THE CONCRETE WALL, REMEMBER THE CAR WAS STILL IN DRIVE MODE AND NOT IN REVERSE MODE, ALL OF A SUDDEN, THE CAR STARTED MOVING BACKWARDS AND EVEN DIDN'T STOP AFTER SLAMMING ON THE LEG BRAKE. THEN I CAME OUT OF THE SHOCK AND APPLIED MY HAND BRAKE AND TURN OFF THE IGNITION TO STOP THE CAR MOVING BACKWARDS. LUCKILY, THIS CRASH DIDN'T CAUSE ANY BODILY INJURY TO ANY THIRD PARTIES BUT I HAD SOME BRUISES ON MY RIGHT ARM DEVELOPED DUE TO SOME METAL PIECES FROM THE TAKATA AIR-BAG.
