THE SPEED CONTROL UNIT WILL RANDOMLY PICK NEW SPEEDS AT IRREGULAR INTERVALS. IN SOME CASES IT WILL RETURN TO THE ORIGINAL SPEED AFTER SOME TIME, IN SOME CASES IT WILL CONTINUE AT WHATEVER SPEED IT WANTS. ONCE SHORTLY AFTER I BOUGHT THE CAR IT STARTED ACCELERATING ON ITS OWN. I WAS ON A LONELY PIECE OF HIGHWAY 395 SO I LET IT CONTINUE UNTIL THE CAR REACHED A SPEED OF MORE THAN 125MPH. BEFORE I WAS ABLE TO TURN THE SPEED CONTROL UNIT OFF.
