Is one pedestrian rule to walk on the left side in order to watch approaching vehicles?

In the US, cars drive on the right side of the road. Pedestrians should walk TOWARD traffic ("against" traffic). In the USA the walker would be on the left side, facing the oncoming cars (but off the road as much as possible). If there is little walking area (say, near a guardrail), the person should move off the road as much as possible and stand still until the vehicle has passed by. This helps drivers by not having to avoid a moving target, especially on narrow roads with traffic coming in the opposite direction.

HOWEVER, bicycle riders must ride WITH traffic, so a bicyclist rides on the right side of the road; vehicle drivers will see the bike rider as the car moves forward. All bikes therefore need reflectors facing the back and on the spokes, to help vehicle drivers to see the bike. The bike should also have a headlight and a horn, and the rider should observe all rules of the road (hand signal before turning; allow through traffic to pass by before taking a left turn; no U-turns; appropriate use of the bike horn to attract attention during dangerous circumstances, etc.)
