You are using the K53 hazard routine and identify a pedestrian near the edge of the road looking at a phone. What is the best next step?

1. Predict that the pedestrian may step out and decide on a safe speed, position and braking plan
2. Assume the pedestrian has seen you because your headlamp is on
3. Sound the hooter continuously while maintaining speed
4. Look away so you do not target-fixate
