I'm not the CT, but I'll chime in anyway...

That is potentially one factor. But also due to ambiguity. With the presence of a BL a driver who glances and sees a cyclist ahead off to the right may just register them as in the BL, then switch their focus elsewhere. This may be fine if the cyclist is fully in the BL, but if on the stripe could lead to a very close pass or even a clip.

While I think this practice has its benefits they are not driven with the goal of exercising legal rights, but instead visibilty and enabling two-way communication with FSDT when it does come. Also I believe that on intersectionless roads, using this technique is not a must do to be a vehicular cyclist.
