Wow, I must be really jaded but I don't think that was unreasonable at all. Looked like 3 feet to me, and that's exactly as I would expect on a road like that. So IMHO and to answer your question directly yes. HTFU.

With that said, it's not my favorite type of road to be on, there is little wiggle room and I'd try to avoid it if there is another good option, but sometimes there isn't so...you can take the lane or part if you want as others have suggested but that's not my method. I say hug the line, keep your line, and get the hell through that section as fast as you can.
