Getting back to that, though... so what makes you "feel" like riding in one position or another when fsdt is not present? Most cyclists - and here's where I'm different - seem to tend towards "as far right as practicable unless there is a good reason to be further left" whether fsdt is present or not.
Oh, any old thing. Road conditions, sometimes, but mostly just because I feel like it. Nice to have a road to yourself. It's fairly rare for a road to be that empty around here, though. Early Sunday morning in a residential area is the usual scenario.
But most of the time I do ride in the bike lane, and the huge majority of roads in recently built south Orange County have wide, clean bike lanes. Which may be part of why this conversion isn't entirely sensible to me, because I can't really imagine intentionally vacating my 15 foot wide bike lane in favor of putting myself in front of traffic.
