Yesterday in downtown, I was in the right tire track of the lane to the left of a RTOL. An SUV in the RTOL swerved right at me from the side to avoid a car that had stupidly stopped in the RTOL. I had the full lane, so I just swerved to the left edge of the traffic lane. At the light, the SUV driver was VERY apologetic. The apology was accepted, and we moved on.
But then I thought, if I had been in a bike lane, I would have had to swerve into the traffic lane to the left, which may or may not have been clear. But thanks to the fact that I was using a full traffic lane, I had 11' or so of space to avoid an accident, instead of 5'.
