I WAS ARRIVING AT MY DAUGHTER'S HOME IN DECATUR GA JUST BEFORE 9:00 A.M. ON FRIDAY, MAY 22, 2015. I PULLED INTO HER DRIVEWAY BUT COULD SEE HERE WAS NO ROOM TO PARK THERE DUE TO THE CONSTRUCTION DEBRIS NEXT DOOR (FROM THE NEW HOUSE BEING BUILT). I DECIDED TO BACK OUT OF HER DRIVEWAY AND PARK ON THE STREET. I PUT THE BMW X3 IN REVERSE AND IT SLOWLY (AS USUAL) BEGAN MOVING BACKWARDS. WITH NO FOOT ON GAS PEDAL, MY CAR CAME TO A STOP AT A SLIGHT INCLINE. I REACHED MY RIGHT FOOT OVER AND TAPPED THE TIP TOP OF MY GAS PEDAL, HOPING JUST A SMALL TAP OF GAS COULD GET ME OVER THE INCLINE. JUST AS I DID THIS, THE PEDAL DROPPED TO THE FLOOR AND THE CAR REVVED, THEN LUNGED BACKWARDS. I WAS HOLDING THE BRAKES AS TIGHT AS I COULD AND WITHIN A FEW SECOND BROUGHT MY LEFT LEG TO HELP PUSH ON BRAKE WITH BOTH FEET. THE BRAKE COULD NOT STOP THE FULL FORCE OF THE CAR MOVING BACKWARDS AT FULL THROTTLE, AND LEFT BLACK SKID MARKS IN HER DRIVEWAY. MY CAR SPEED IN REVERSE AT FULL THROTTLE ACROSS THE STREET NARROWLY MISSING A DUMPSTER PARKED NEXT DOOR AND ANOTHER VEHICLE DRIVING UP THE STREET WHO WITNESSED THE INCIDENT. MY CAR PROCEEDED INTO THE NEIGHBOR'S YARD (DIRECTLY ACROSS THE STREET), CRASHED INTO THE NEIGHBOR'S CAR, PUSHING THEIR CAR INTO THE FRONT PORCH OF THEIR HOUSE. BOTH CARS WERE TOTALED AND THE HOUSE SUSTAINED DAMAGE. THIS INCIDENT MUST BE INVESTIGATED. PLEASE CONTACT ME FOR MORE INFO AND TO GET ACCESS TO MY CAR FOR INSPECTION. PEOPLE COULD HAVE BEEN KILLED!!! *TR
