. ON THURSDAY, 11/7/13, I GOT INTO MY CAR TO GO TO WORK AND THE DASHBOARD GAUGE INDICATED THAT AIR PRESSURE IN ONE OF MY TIRES WAS LOW. I LOOKED BUT THEY APPEARED TO BE OK. I HEADED TO MY MECHANIC INTENDING TO STOP THERE ON THE WAY TO WORK. THE CAR PERFORMED NORMALLY ON THE STREETS AND THE HIGHWAY. MY FOOT WAS ON THE BRAKE AS I ENTERED THE EXPRESSWAY DECELERATION LANE TO EXIT, CAR STILL FINE. I PROCEEDED DOWN THE EXIT RAMP, MY FOOT NEVER LEAVING THE BRAKE PEDAL, I APPLIED A BIT MORE PRESSURE TO THE BRAKE WHICH INITIATED A "FLAT TIRE" , BUMPY SORT OF RIDE. I SLOWLY KEPT BRAKING ON THE EXIT RAMP WHEN THE CAR SUDDENLY ACCELERATED, MADE A 90 DEGREE TURN TO THE RIGHT, STRAIGHT INTO A RETAINING WALL, THE CAR WENT UP THE WALL (OFFICER SAID THERE WAS A MARK ON THE WALL ABOUT 10-11 FEET UP), FLIPPED OVER AND LANDED ON IT'S WHEELS. I HAD ABSOLUTELY NO CONTROL OF THE CAR, COULDN'T STEER OR STOP IT. NO KEY TO PULL OUT... PUSH BUTTON STARTER. AIRBAGS DID NOT DEPLOY. I SUFFERED A FRACTURED STERNUM , FRACTURED SACRUM (DUE TO MY WEIGHT ON THE SEAT BELT AS THE CAR HIT AND TUMBLED) PLUS OTHER INJURIES. CAR WAS TOTALED. YOU WOULD THINK FROM HITTING A WALL TO FLIPPING TOTALLY AROUND, SOMETHING WOULD TRIGGER AN AIRBAG TO CUSHION ME AGAINST BONE FRACTURES. AND THIS WAS NOT A CASE OF REACTIVE BRAKING (HITTING THE ACCELERATOR BY MISTAKE)...MY FOOT NEVER LEFT THE GAS PEDAL FROM THE DECELERATION LANE ON HIGHWAY TO VERY SLOWLY DESCENDING THE EXIT RAMP. LOST MY JOB, NO SICK PAY. WAS SCHEDULED TO TAKE
