The rule we teach in this case is to "leave room for cars." The idea is to have a number of clusters of 12 to 20 riders, separated by a couple hundred yards of road space. Yes, drivers have to make multiple passes, but it's a lot easier for them, and safer, than trying to pass something like the peleton of the Tour de France... very much like trying to pass a freight train on a narrow 2-land road.
It's also better to keep the groups together, in a pack, rather than having single riders or little groups of two and three scattered up and down the roadway 10 or 20 yards apart, leaving no real safe space to try and pass. That's what gets drivers jacked up more than anything other than filling the whole roadway like a swarm of bees. The advantage that we riders get from that is that the larger groups are more visible to others than the single riders putting along.
Riding no more than double file is the law in most states. Arkansas is one of those that doesn't address riding abreast, thus single file is technically the law here. You can generally get by with riding 2 abreast, though.
I've taught the LAB Group Riding Skills clinic for about three years now, and it's amazing how 30 to 50-year-old cyclists have trouble with simple arithmetic and counting... as witnessed by how many times I've had to pull the class over to the side of the road for a quick Teachable Moment that starts with the question, "Okay guys... Some one please tell me, how many is Two?"
