don't use clips, but have toe straps so similar. usually I will stand on my right leg when I get off the bike, so right - this generally has the effect of forcing vehicles to give me more room or wait for me to move away first.
(I will add this has come about from not having full control over my left foot from various accidents/dog bites and it is the one I have trouble getting into the toe strap, so 'unclipping' with my right make more sense in my case.0
