on higways I like to stay in the right hand position of the far most left lane. You have less to worry about, because people are not getting on and off. Slow down speed up. Like a far right hand lane. If the highway is a couple of lanes wide. That will also eleminate anybody for the most part mearging from your left. I ride in the right lane position, becuaes I feel that, that is the best spot you are going to be seen. I never ride center and left had lane you are hidden. I usually try to only go a bit faster then traffic on my right, if you are flying by people you are a target.
