How should a pillion passenger behave while the motorcycle is leaning into a high-speed curve?

1. Lean their body aggressively in the opposite direction of the turn to keep the motorcycle upright
2. Turn around to take landscape photos with both hands off the grab rails
3. Remain relaxed, keep feet firmly on footpegs, hold the rider's waist or grab handles, and lean naturally with the motorcycle without fighting the lean or shifting weight abruptly
4. Put their feet down toward the road surface to stabilize the bike
