Serge:
As you may remember from other threads, I am a supporter of vehicular cycling. However, I would like some clarification regarding this last statement.
So, you are riding along in heavy traffic and encounter a long line of cars stuck in the traffic. You have the choice to sit in the traffic with them for the next half hour or move to the front. I vote move to the front. Are you saying it is safer to pass them along the yellow line, splitting the lane with oncoming traffic than it is to pass along the curb?
