Primary riding position: A "centerish" "lane controlling" position in the traffic lane somewhere between the left and right tracks.
Seconary riding position: About 3 feet to the right of faster overtaking traffic.
This is one method for riding on roads with bike lanes:
Even on roads with bike "lanes", ride out in the traffic lane in the primary riding position EXCEPT when faster traffic is present or is approaching (monitoring for which a mirror is very useful). When faster traffic is approaching, right shoulder check and merge right to a lateral position approximately 3' to the right of passing traffic (which may or may not be in the bike lane), until they have passed, and then left shoulder check and merge left back into the traffic lane again.
The behavior that results from doing this is similar to that practiced by other drivers of slow moving vehicles. For example, when riding my 1972 Honda Trail 70 at under 20 mph on steep streets, I generally ride in a visible/predictable/centerish position, but merge right to allow 35+ mph car drivers to pass when they're behind me, then merge back left when they've passed. This behavior is also consistent with how truck, tractor and other heavy equipment drivers sometimes temporarily merge right into shoulders to allow faster traffic to pass under certain conditions.
Obviously, on roads with constant busy traffic, a cyclist using this method would spend much of his time in the secondary riding position, which often means being in the bike lane. But, the entire time, monitoring to the rear periodically and frequently, looking for significantly large gaps in traffic. When (if) there is a gap, left shoulder check and merge left, until another need arises to merge right to allow approaching faster traffic to pass.
Surprisingly, most roads at most times don't have sufficiently constant traffic to render this technique moot, as some may think, even during commuting times (largely thanks to traffic signals). If one starts looking for significantly long gaps in same-direction traffic and using them, one may find they are much more prevalent and longer in duration than many might realize. So using the primary position per this method occurs quite regularly, even on relatively busy roads. The (huge) bonus of this method is that it automatically puts you in or near an excellent lateral position in terms of sight lines and conspicuity any time you encounter any kind of intersection, or if the lane narrows, or if you're on a 2-lane road to discourage oncoming traffic to pass in your lane, etc. A secondary bonus is that being in the primary rather than secondary position makes you more conspicuous to those approaching from behind, which in turns makes it less likely they they will be unaware of your presence as they overtake you (by which time you would be out of their path in the secondary position, if it's safe and reasonable to be there). Another secondary bonus for using this method is that you spend less time riding in rubble and debris.
When riding on roads with bike lanes, do you use the method above described in blue? If so, for the reasons specified, or for other reasons?
If not, what method do you use instead, and why?
