I dont know about you guys,but when I have my doubts about cars at junctions,I get ready to brake,but also I put myself nearer to the middle of the road,that seems to confuse them and they hesitate just long enough for me to pass by safetly.Normally I ride either side of the center of my lane(oils and undesireable slippy stuff is in the middle),(and drain grills and manhole covers dependent) use the road I'm in like I'm in a cage.Dont much care what the drivers behind me think of my riding,it keeps them at a respectfull distance,and me(most importantly)safe.
