Why do so few pedestrians know?

I've studied road rules in a couple of different places and can find this advice online. And yet either few pedestrians hear of it or pay attention.

If you are a pedestrian walking along a street - walk FACING the traffic.

 "Always walk on footpaths or nature strips where possible. If there is no footpath or nature strip, walk so that you are facing oncoming traffic."

We walk dogs daily and very very few other people walking/jogging on the streets ever do this.

FACE the cars and live!
