WE WERE SITTING IN "BUMPER TO BUMPER" TRAFFIC ON A DOWNWARD INCLINE, WHEN THE CAR AHEAD OF ME MOVED FORWARD ABOUT 8 TO 10 FEET. I TOOK MY FOOT OFF THE BRAKE TO COAST FORWARD ALSO, BUT MY CAR MOVED AT A FASTER RATE THAN I ANTICIPATED. I QUICKLY TRIED TO BRAKE THE CAR AGAIN, WHEN MY FOOT CAUGHT UP ON SOMETHING IN THE PROCESS AND I COULD NOT DEPRESS THE BRAKE PETAL. IN TWO SECONDS I WAS INTO THE OTHER CAR. THE OBSTRUCTION PROVED TO BE THE BRAKE LIGHT BOOT SWITCH. UPON INQUIRY LATER, MY DEALER SAID THE BOOT SWITCH COULD NOT BE CHANGED OR MOVED, WITHOUT A REDESIGN BY THE MANUFACTURER, FORD. *AK
