When do you take the lane?
(If this is in the wrong section, please move)
Quick senario. About a week ago I was driving on a curvy 2 lane road (1 lane each direction) with a narrow shoulder. From the white line to the edge of the road was probably about 2 feet wide at max. There was what looked like a pretty experienced cyclist on a nice road bike ahead. He was positioned, for the most part, on or a little to the right of the white line in the shoulder. I have never biked on the particular section of the road. I would think he would have been better taking the lane in the right tire track to make himself more visible, especially on a curvy road. I could be wrong though.
So I'm just wondering, when do you personally decide to take the lane? I know people have different views on it, but what is your preference? Also, if there's a decent shoulder and you use it, where do you position yourself in it?
