¹IANAL; in the jurisdiction I'm in, but my understanding is that this is common
Yeah, I perhaps should have made it clear that occupying a full lane is something I do probably <2% of the time. Not very often, and for similar reasons to the rest of the comment: I don't really want to have to deal with cars, and if I can stay right and let them by, I will.
I'm in America, so it depends on the road; where we have unprotected bike lanes, then I'm in that & there's passing room, but too often there are "sharrows" where there really isn't a good deal of room for passing. Then it's very situational. (Usually the car taking up part of an oncoming lane as they pass.)

He eventually did a half lane change, buzzing me as he went by, then got stuck at the next red light while I caught up. Ridiculous.
(Of course my area also has reckless motorists who don't respect the rules of the road, but they seem to believe they are above the law whether they are interacting with cyclists or other motorists.)
