ON MAR 1, 2021 WHILE DRIVING SUPER CRUISE MODE, MY CAR JERKED VIOLENTLY TO THE LEFT ALMOST STRIKING ANOTHER CAR. I WAS ON THE FL TURNPIKE ABOUT 20 MILES NORTH OF ORLANDO HEADING SOUTH. THE HIGHWAY WAS INCREASING FROM 2 LANE TO 3 LANE SOUTHBOUND AND I WAS IN THE RIGHT LANE. WHEN I ENTERED THE LANE TRANSITION, THE CAR DRIFTED RIGHT . AS THE CAR CAME UPON THE NEW WHITE LINE THE CAR ABOUT CENTERED IT. THE CAR TURNED HARD LEFT, AND TURNED OFF SUPER CRUISE. FORTUNATELY, I WAS ABLE TO GRAB THE STEERING WHEEL AND CORRECT THE TURN. WE DID NOT CRASH, BUT IT WAS MOST UNSETTLING.
