I much prefer quieter roads; or better still traffic free cycle routes like disused railway lines. I don't think it has anything to do with confidence; I have plenty of confidence in my riding ability, having done it for nearly 50 years. What I don't have confidence in, is drivers ability to avoid colliding with me through their inability to concentrate on what the F*** they are doing rather than faffing around with phones, satnavs, razors, make-up, DVD players, arguing with passengers, etc. etc..
