I'm right handed, and unclip ambidextrously. I unclip whichever foot needs to go down at the time. Usually that's the right, to stop at a curb/stoplight, but sometimes it's the left, if I'm in the left turn lane, for example.

So I couldn't participate in the poll, because it's only my feet that are ambidextrous! I'm pretty aggressively right handed. I used to say that my left hand was there for decoration only, but then I began to appreciate all the things my left hand does. It does a lot. Props to the left hand.
