That's almost a sure way to wind up under a car. In some cases taking up a lane is realistic, but if you take a lane and cause a motorist to miss a light, or if it seems even a tad on the self righteouss side of things, you will be staring down the barrel of an escalade pretty fast. The road rage you will incite given the wrong person behind the wheel may just get you killed. I learned a long time ago that you have to treat cars like bulls in the ring, you have to charm them, communicate with them, and always keep your eyes on them. And NEVER paint a bullseye on your ass by taking up a full lane when it isn't absolutely necessary and reasonable to do so.There is a reason bicycles are supposed to go down the middle of the lane, not hug the curb so closely, that pedestrians standing to cross the intersection are at risk of being hit.
I clearly remember being instructed when I was in school many decades ago, to not go down the edge of the lane, so that you aren't hit by things like doors.
I'm not sure why cyclists in Toronto fail to assert their right to the entire lane. By not doing so, they take away one of the safeguards they have against accidents.
At the same time, car drivers must watch out for these things.
