I just began using clipless pedals yesterday. Have to say it worries me at low speeds and near traffic. I usually unclip the left foot but leave the right foot cliped when coming to a stop. Totally forgot about it and kind shifted balance to the wrong side while my foot was clipped. Thank god I just balanced for like 2 seconds until I managed to put it back on my good foot. It was scary. Somehow I feel like falling from that height can really hurt.
