So basically you are riding in a very wide paved shoulder to the right of the fogline?
I might ride there, if, like Brian and richard said, you are careful when merging back into the lane before the shoulder narrows down. Three other considerations:
- Drivers crossing your path from the left or right might not look for vehicles in that area.
- There could be a debris or a crappy surface, requiring you to swing suddenly into the traffic lane.
- There could be pedestrians walking there or cars stopped there, also requiring a quick return to the traffic lane.
So, I might ride there but I would be extra careful.
