After riding 20 miles at 5-15 mph, I am suddenly a supporter of this. Maybe I guess if it's legal to do so, and there was enough room I would do it. But I couldn't see riding my bike on the dashed line between lanes of cars that were moving. Where is this legal? I guess my dislike of the practice in the past was I didn't know it was legal in some states, so seeing made me shake my head. But if it is legal, who am I to disagree.
