There is a short section of busy road, about a mile and a third long that I used to commute on.
It has no outside shoulder, unless you count the soft, glass filled and manhole infested space there.
It does have an "inner" shoulder, quite wide enough for a small car. I started using it before
I looked up the rules, which state something like "as far to the right as practicable or on the shoulder"
I would loiter in the merge lane or stop to the side while watching the traffic in my mirror, and when clear, sprint across to the shoulder, and continue there, watching traffic in my mirror as I did so. At first, I noticed a police car or two, slowing slightly, I'm sure they considered the legality and safety of my technique, then decided it was legal and the best option.
The road is fast, constricted, has a curve, lots of distractions, and is notorious for bad behavior. Taking the lane is not something to do without massive strobe lights.
What would you do?
