Did my first big ride today 200+k's but due to being on L's, had to say under 80. This made me a moving road block on the highway. The prize idiot of the day, in fact of this decade and the last, decided to use the half of the lane I wasn't using to overtake me. He had 15kph of overtake on me and passed 30cm from my right knee, all while his right wheels were over the double yellow lines with oncoming traffic! I tried to work out how I could have avoided this, and others have pointed to lane position. I was about 20cm left of dead centre in my lane when the idiot made his move. Should I have stayed in the right half of my lane, closer to oncoming traffic? I had stayed left to maintain the greatest safety space from the obstacles around me ie. oncoming traffic, while improving my rear vision in my right mirror(finding the lack of rear view the hardest thing to get used to) Any thoughts?
