I just had a thought for people just going to clipless - maybe try what are called campus pedals. These are pedals with one side that is clipless and the other is just a regular pedal. That way you can clip in just when you want. My sister has always used these because the idea of completely clipless just never appealed - the idea of being in traffic and not being able to unclip, that whole thing. Shimano has a pair that are quite nice. Anyway, this might be a way to ease into the whole clipless thing.
