There's been a lot of interest in clipless pedals lately in this forum. A lot of our members have been using them for some time, and a handful have changed over recently, or are doing their homework to figure out what kind of pedals and shoes will be best for them. With anything that attaches your foot to the pedal comes track stands. At least if you live in an area with stop lights and signs.
They're not quite as useful/almost necessary with clipless as with toe clips, since you don't have to lean down, loosen the straps, and then tighten them again, but it's still more convenient to avoid clipping out, if possible.
I track stand at lights, even though I have derailleurs.
