How many of us bike commuters have spouses who are almost overcome with anxiety and worrying while we're out riding to or from work? What have you done, if anything, to help overcome your spouse's fears?

Earlier this week it was reported a cyclist was killed on a state highway in my county. Later the details came out that the guy was from Canada, riding to New Orleans, and was riding on the wrong side of this 65-MPH divided highway (has traffic lights so not limited access). Apparently he "swerved in to the traffic lane" and was creamed by an 18-wheeler.

The next day I wanted to take my son to swimming lessons with the bike and trailer. My wife practically begged me not to because of hearing about that other cyclist the day before. Then she also said every time I ride to work and come home after 6 in the evening she's always worrying that I may not make it.

While that cyclist death is a tragedy of course, he was doing a lot of things wrong. I always wear high-viz, have BRIGHT flashing lights, use a mirror, ride WITH traffic, and use the full lane by default in most cases. It works for me very well. I tried to explain those things to my wife but it didn't do much.

Is there anything I can do to reassure her? Maybe some iPhone app where she can look on hers and see where I am, and see that I am "in motion" while coming home from work?
