I don't find this type of road as obnoxious as one where the shoulders get obstructed by drains and rumble strips because in those situations, cars have less understanding of why you aren't on the shoulder, e.g.
Your photo was very good at capturing the rumble strip. I took this photo because more than the left half of the shoulder was rumble strip, but the photo did not capture it well, that is a slightly darker gray but if you were not there to ride it you would not know from this photo that the rumble strip could shake the teeth out of your jaw.
The non-rumble strip of shoulder along the right side edge was roughly a foot wide, which would be difficult to ride for any distance if you did not have wind gusts. But, there were wind gusts.
And of course the cable median means that the big trucks and busses can't give you much space if they wanted to.
