Regardless of that woman getting mad and her dangerous aggressive actions....

When you are in the right shoulder, passing on the right a line of cars stopped for a light or a stop sign, you are putting yourself in real danger. You are creeping along in every driver's blind spot, one after another, and they are all about to start moving and are looking forward- they are not watching for something to suddenly cut in front of them from the right shoulder of the road behind them.

Is getting a head of a few extra cars at a stop light worth giving up your life for? Something to think about.
