that's not what I'm suggesting!

Such a propensity to posture contrived arguments as if other people are making them.
john, you just affirmed straddle lane overtaking is acceptable when safe to do so -
"it really doesn't matter whether he makes a full lane change or just a straddle" - you also seem to think it doesn't matter if motorists partially change lanes to pass, so long as its safe. A riding dynamic most of us can agree on.
what IS clear in this sideline to the discussion - when the opposing lane, a center turn lane, or an adjacent lane allows it, safe overtaking by straddling a lane line is acceptable in the Bicycle Driving canon.
.....So long as in Maryland the overtaking is legal and with at least 3 feet of clearance.
( It is interesting, and alarming, however, that bike specific passing clearance laws are opposed by most bicycle drivers as being 'discriminatory' towards bicyclists

)
The research looked at passing clearances and compliance with the new Maryland law in Baltimore.
the findings indicated greater compliance with the law along roads with bikelanes - indeed, none of the passes of bicyclists in the bikelanes were closer than 3 feet in the study.
