And when you are in the physical therapy waiting room to see about your repetitive stress injury maybe you will remember all the fun you had wagging your finger at others.

I've had two close calls on the road in the last 2 weeks. I'm sitting here writing from my house, as opposed to a hospital bed, because the driver 2 days ago awoke out of her trance just in time. Honestly, I'd have felt a little better about the experience if this had happened a few milliseconds and a few feet earlier. As for the earlier incident (a "right hook"), riding defensively avoided a major problem, but the ability to signal my location might have prevented the incident altogether.
