I know what it means. I know that when I approach a red light on my bike, if I'm the first person at the light in the right lane, I move a little to the left of my position in the lane (although if I'm a solo cyclist, I worry about a distracted driver not seeing me in the way). I know that if a car is in front of me, I get in the middle of the lane behind them, and as I proceed through the intersection I move to the right again. Meanwhile, while I am at a light, in whatever position I am in, I am constantly looking around me, and if I see an approaching car acting like they don't see me, I move as fast as I can. It's one reason why I don't like riding (or running) with headphones on. I need to hear what is going on around me, I don't feel safe if I am handicapping one of my senses any more than aging is already doing.

Even though I made a rookie mistake with my SPD pedals, I'm not a novice bicycle rider. Many years ago as an avid road cyclist, I was also on the Urban Area Bicycle Advisory Board for Gainesville, FL and Alachua County, FL. But I am also a motorist way more than I am a bicycle rider, and knowing the rules of the road and the accident statistics in car vs. bike encounters, it does not make me happy when I see bicyclists behaving carelessly while riding.
