Great post!

And I think this exact same way while I'm riding:

I take the space I need, which means that if I think a lane is too narrow for the car and myself (or, approaching a turn, if I think we shouldn't go in there side by side), I just make sure that the driver will see it's not possible to share the lane. As soon as it's practical for me to move back to the right of the road, I do, and motion the car to pass me if it's safe to do so.
