Glad you are better, I really do question why I still commute on the pedal bike these days. My commute involves a 2 mile stretch of B road where some people hit three figure speeds. I suspect I wouldn't know much of what happened for the worst occur, but it not exactly fair on the family to be left without me all of a sudden.
I've really questioned the point of using the pedal bike on/off the last few years, increasingly so, I think I'm leaning towards just driving. I really do love cycling so much more than driving these days, but as you say, flesh & bones is no match against metal on wheels.
