I just started w clipless in middle of March this year. I 'taught' myself and just naturally went to unclipping right. Fell 2 times at stops when I unclipped but forgot to lean enough weight to the right and did a sloooww topple to left. Luckily nowhere near traffic(I'm new remember!). Anyway love this thread. When I first started biking last Sept I just always pushed off with left foot and stopped with right foot down first so the SPD just followed suit. Also can only mount from left (I feel silly because I tried once or twice from right but can't get it together so....and I have to walk my bike on left side too.
