It is amazing what you can get use to and clipless pedals are worth the effort and focus. I not only commute to work but my idea of a vacation is long days in the saddle exploring the terrain (cyclo-camping). Being clipped in allows for efficiency and comfort. I've fallen several times when i was younger- going up a steep incline and lost momentum clipped in and bam! Talking to a friend leaning against her van and totally taken down by this impromptu situation and as i tried to step off- boom! Just bumps and bruises and as i go through my 50's I've already have learned all those little tricks like unclipping before intersections or stops. I seldom clip in city traffic. Of course, steep hills are a cause for me to unclip also:-)
