I agree, as long as the cyclist uses his head and remains on the edge of the straight lane, there is no danger from cars going straight or turning. Really, people need to be informed when riding or driving and make good choices.
I watched a cyclist this morning take a right turn lane at a 3 way stop and loop around the back of the oncoming lane between 2 cars to avoid the stop sign. He endangered his own life obviously, but his confusing and dangerous lane changes also endangered drivers. Its no wonder some people hate us. He could easily ridden to the stop sign, stopped and taken his turn thru the intersection. Putz. Thats why some municipalities put up no bikes allowed signs.
