I can't say I think about it all that much. But because of this thread I might think of it more. In 2 years and many thousands of miles commuting on rural 2-lane roads, I can only recall one time where I really came close to having to bail, when this motorist tried passing me over a blind hill as I continued to motion for him to stay back, and another car came the other way right over the hill. That was scary. Otherwise I use various methods and techniques that keep me as conspicuous and predictable as possible.
