TWO COLLISIONS AND SEVERAL OTHER INCIDENTS WHERE I WAS DRIVING 40-60 MPH, THE CARS IN FRONT OF ME SUDDENLY BRAKED, AND I IMMEDIATELY BRAKED WITH ENOUGH TIME AND DISTANCE TO COMPLETELY STOP THE VEHICLE BEFORE COLLIDING WITH THE VEHICLE IN FRONT OF ME. EACH TIME, ALTHOUGH I SLAMMED MY FOOT ON THE BRAKE IMMEDIATELY, THE CAR FELT LIKE IT WAS BRAKING, BUT NOT NEARLY AS FAST OR AS INTENSELY ENOUGH GIVEN THE AMOUNT OF PRESSURE I WAS APPLYING TO THE BRAKES AND THE TIME AND DISTANCE I HAD TO STOP BEFORE REACHING THE CAR IN FRONT OF ME. IN TWO OF THESE INSTANCES, WHERE THERE WERE CARS IN THE ADJACENT LANES, I WAS NOT ABLE TO SWERVE AWAY TO AVOID THE CAR IN FRONT OF ME, I COLLIDED WITH THE CAR IN FRONT OF ME. IN OTHER INSTANCES, I WAS ONLY ABLE TO AVOID A COLLISION BY SWERVING INTO ADJACENT LANES.
