WHILE TRYING TO STOP MY FORD F-150 TRUCK, I WAS ACTUALLY HITTING THE ACCELERATOR AT THE SAME TIME AS I WAS PUSHING THE BRAKE PEDAL. I COULD NOT TELL THAT IT WAS HAPPENING UNTIL IT WAS TOO LATE. AS I PSHED ON THE BRAKE THE TRUCK DID NOT SEEM TO SLOW DOWN NEARLY AS FAST AS IT SHOULD HAVE, SO I PUSHED HARDER ON THE BRAKE AND THAT DID NOT SEEM TO WORK PROPERLY, THEN I REALIZED THE RIGHT EDGE OF MY FOOT WAS ACTUALLY DEPRESSING THE ACCELERATOR, BUT YOU COULD NOT REALLY FEEL IT SINCE IT HAS VERY LITTLE RESISTANCE. WHEN I REALIZED WHAT WAS HAPPENING, I TRIED TO LIFT MY FOOT OFF THE ACCELRATOR, BUT TO DO SO I HAD TO RELEASE THE BRAKE A BIT. WHEN I DID THAT, THE VEHICLE LURCHED FORWARD TOWARD THE CAR IN FRONT OF ME AND HIT IT. IT HAPPENS BECAUSE AS YOU ARE HITTING THE ACCELERATOR WHILE TRYING TO BRAKE, THE ENGINE REVS UP TO HIGH RPM, AS YOU TRY TO GET YOUR FOOT OFF THE ACCELERATOR, AND RELEASE THE BRAKE A BIT, THE CAR THINKS YOU WANT TO GO FAST AND TAKES OFF BECAUSE OF THE HIGH RPM. THIS HAPPENED TO ME ABOUT TWO OR THREE WEEKS AGO, BUT IT JUST SEEMED LIKE AN ODDITY AT THE TIME SO I DID NOT REALLY THINK IT WAS A BIG DEAL. THEN IT HAPPENED TO ME AGAIN YESTERDAY WHEN I NEEDED TO STOP QUICKLY BECAUSE EVERYONE HAD SLAMMED ON THE BRAKES IN FRONT OF ME, SO WHEN I WENT TO HIT MY BRAKES, I INADVERTANTLY WAS HITTING THE ACCELERATOR AT THE SAME TIME AGAIN, ONLY THIS TIME, IT CAUSED AN ACCIDENT AS I PLOWED INTO THE CAR IN FRONT OF ME. I HAD PLENTY OF ROOM IN FRONT OF ME, AT LEAST 10 TO 1
