The drivers that know how to win don't always look like they are going fast - they know how to drive smoothly and maintain control of their cars. Other competitors listen to their times and wonder where they are going so fast - everywhere. All your inputs to the car - steering, braking, and shifting should be smooth, controlled, and well timed. All sudden and abrupt inputs to the car will cause it to be unbalanced on the suspension, lose cornering speed, and cost you valuable time. Smooth driving is a skill gained with experience and practice.
