What is the correct way to handle a rear-wheel skid (oversteer) in a rear-wheel-drive car on a slippery surface?

1. Steer smoothly in the direction of the skid (into the direction you want the front of the car to go) while easing off the accelerator
2. Slam on the brakes immediately and turn the wheel in the opposite direction of the skid
3. Accelerate aggressively to spin out of the slide
4. Pull the emergency handbrake instantly
