Wow, I am really in the minority here. I am right handed but always unclip RIGHT. I do like that that makes the lean before stopping against traffic, but I don't know if I consciously learned to do it that way for that reason. I think, actually, that my DH taught me to use clipless years ago, and that's the way he did it, so that's just the way I learned. He is also right handed, btw. It feels totally foreign to even imagine doing it the other way, but now that I am mountain biking more than road riding, I've been told I really do need to get comfortable unclipping on either side. There is even a skill when going around a tight turn/switchback to unclip the inner foot, put it down and kinda pivot the bike around the turn if you can't make it without putting a foot down. I can kinda do this on a right turn since that's the side I unclip on, but haven't dared to try it on a tight left yet.
