Judging by some of my fellow commuters (not anyone on this board, of course), I wonder how it is that so many people have no clue how to stop and start a bike. I see riders coasting up to intersections, and then staying in the saddle, trying to balance on tippy toes during the red. When the light turns green, they shuffle-shuffle en pointe (can't be good for the shoes), and try to put both feet on the pedals at the same time. A couple riders wobbled so much I was concerned they'd fall into traffic.
