If your vehicle's accelerator pedal becomes stuck in the fully depressed position while driving, what is the safest recovery sequence?

1. Shift to Neutral, apply brakes firmly, steer to a safe area, stop, and turn off the engine
2. Slam the gear shift into Park (P) while steering toward a wall
3. Turn off the ignition key immediately to lock the steering wheel
4. Pump the accelerator pedal repeatedly while applying the handbrake
