This. My wife has never had a problem with my bike commuting (except maybe a little when I'm riding in the dark). Lately she has been riding part of my commute with me -- she turns around at about 9 mile mark and heads home.
Your wife's fears are based on lack of knowledge, and the only way that will change will be to take her on the ride.
