First - what a video! It is morbidly fascinating and horrible. Metric Man: I wish you the best for recovery and hope you're riding again soon, with little or no paranoia.

I'd like to preface my question with the statement that I am in NO WAY faulting the cyclist for anything. I'm wondering though if people tend to ride close to the white line? That seemed to be a broad, clean shoulder. I tend to ride closer to the middle or even edge of the shoulder assuming it is relatively clear of debris. Ideally, I'd like the high speed traffic to be able to pass me w/ 3 feet of clearance without drifting over the striped center line of the highway. If I'm close to the white line, they either have to pass closer than that, or move out of their lane - I don't like making anyone do that if not necessary. (If necessary, I don't mind making them do it!)

A lot of time, the further you get from the white line, the more crap is on the shoulder, so you have to ride closer to the white line, so it's not a cut and dried thing for me or anyone.

I don't want OP to respond to this because I in no way want it to be an issue in this. But I'm wondering where other riders default to - closer to the edge of the shoulder or closer to the white line.... and why.

I'm lucky that most of the highway riding I do is on a shoulder with rumble strips. I think they tend to keep the drivers from drifting inadvertently and also give me a heads up when someone is drifting -although in my opinion, there's little or no chance of changing my line to avoid being hit from behind, even with visual (mirror) or audible (rumble strips) warning.

All my best to you Metric Man. Don't take my question as a fault, just genuine curiosity about riding habits.
