Final answer:
Excessive centrifugal force will pull a vehicle across the centerline and into oncoming traffic when driving in the inside lane of a curve. This is a result of the body's inertia and the lack of sufficient centripetal force provided by friction between the tires and the road.
Step-by-step explanation:
When driving in the inside lane of a curve, excessive centrifugal force will pull you across the centerline and into oncoming traffic. This sensation is due to what is called the 'fictitious' centrifugal force, which makes you feel like you are being pushed away from the center of the curve. This force is not an actual force acting on you, but a result of your body's inertia, as it attempts to continue in a straight line while the vehicle is turning. In reality, the centripetal force is what is acting on the car, pulling it toward the center of the curve, and is provided by the friction between the tires and the road. When this friction is not enough, such as on ice, the vehicle will tend to move in a straight line off the curve due to Newton's first law.
