Final answer:
When driving through an ideally banked curve at appropriate speed, you wouldn't feel thrown to either side due to the centripetal force exerted by the car seat, which counters the centrifugal force.
Step-by-step explanation:
When you negotiate a curve that is ideally banked for your car's speed, you would not feel yourself thrown to either side. This is because the banking of the curve is designed to match the horizontal centrifugal force acting on the car due to its velocity.
The force exerted on you by the car seat would be directed towards the center of the curve, providing a centripetal force that keeps you in a stable position relative to the car.
The seat exerts this force to counteract the centrifugal force that wants to push you outward towards the door. Instead, you feel pressed into the seat, which is comfortable and ensures that you don't slide around while the car is turning.
