I think that dav is right - until some of these people end up in an accident themselves they will never seem to learn, unfortunately. Like an alcoholic who won't/can't admit that he has a problem, or else they think that they're somehow superior, and"those cell-phone problems only happen to other people who cannot keep their attentions focused, but I don't have that problem". Sad. Hopefully they are nowhere near any of us when the great realization is thrust upon them.
