Um, 3speed, bikes are traffic. Often times it is much safer to take the lane, and legal too. Ever been right hooked? I do not stay to the right of moving cars through an intersection. Too many M*******s ( good word for the day) drivers do not use turn signals. Do I stay in the middle of the lane always, not at all. I use good sense to try to keep me safest. One of my "fun" sections of busy roads involves a two lane road with the right hand lane being an on ramp for 128 North and south , about 150 feet apart. I bike in the middle of the righthand lane, cars can go around me or stay behind me to get on the highway. Works for me, YRMV.
