In my experience as a biker (and pretty much all the fellow bikers I've talked to) it's much safer to ride in the middle of the lane. One, riding to the side of the road invites unsafe passes, people are much more likely to make unsafe pass thinking what's the big deal if you bike as far to the side as possible. Two, paradoxically, I've found people give me much more space when passing me when I ride in the middle of the lane, if I ride in the middle of the lane they are much more likely to completely move over when passing me giving me good 3-5 feet of space, when I ride to the side of the road, they will often give me only 1-2 feet of space when passing me with throttle wide open.
So yeah, all it takes is one dickhead, but dickheads aside I'm much safer riding in the middle of the lane.
Agreed - far safe in the middle.
I ride on the right side (~20% of width) of the road. If there is a bike line, I definitely do that. The only time I take the full center is if there are many cars parked on the side - crashing into an opening door is something I want to avoid. The other instance is if the side of the road is poor road surface that is full of pot holes and debris that might lead to a flat tire.
Its amazing how angry and irrational someone can get when there is a cyclist doing completely the legal thing. Most times, if I'm in the middle, and its clear, i'll move over to let cars easily - sometimes they give a light tap on the horn because I may not hear them, and then I move to the side when it is safe. My issue is a car comes up, gives about 0.5 seconds and starts honking like mad or pulls in within a foot to intimidate me. I wish cops were around.
For everyone complaining - get all legal codes changes that prevents bicycles from cycling on the road. Until then, stop inventing claims that rules regarding cyclists somehow don't apply.
