Now I am not sure if I think in SS terms re bikers according to my boyfriend, or not - so just saying I *would* have thought it reasonable to expect a super large group of bikers (50 plus or whatever, which I know can happen during bike week) to allow for cars in left lanes to get over mid-bike pack in order to get to an exit from a highway. My boyfriend, who is if anything more inclined than I am to see see things from other's perspectives was adamant on this one.
As he is the biker, not me, I will just share that his immediate firm reply was, no, the bike pack does not need nor should shift or make rrom for other drivers to switch lanes, the car driver should either plan well ahead or go to the next exit.
As a non-biker, I would not have necessarily seen it this way, and will admit I am surprised.
Also, I offer this not to say it is the "right" view, just to say that at least one biker who is generally "over considerate" on many points does see this as an absolute.
