I would be careful if there were alot of the repaving marks like you have in your photo, but I would be riding about one foot to the LEFT of the white line, until I saw/heard traffic coming up from behind me. The I would scoot over to the center shoulder like the rest of you. I ride out in the main lain because
(1) I have a better view of the road when I am out on the main portion.
(2) the road surface often has a better grade of tarmac than the shoulder.
(3) the road surface is usually cleaner thn the shoulder, even if the latter is swept.
(4) cars see me sooner when I am on the main lane; and when they see me respond, the become aware that I am aware of them.
(5) I can use my rear view mirror to monitor their response as I move back toward the right.
