Riders with platforms need to weight both pedals simultaneously to keep their feet from flying off, thus forcing the legs to work against each other. Regarding feet flying off, I saw a lot of this during my first (and only) triathlon, in 1985. Several riders were stopped on the side of the road on one bare foot, trying to extricate a running shoe wedged between the spokes of the front wheel and the fork.
Serious cyclist need something to keep their feet on the pedals. Clip-less pedals and cycling shoes are certainly the way to go. But if you don't want to carry a "shoe bag" for your trip to work, the coffee shop, or whatever.... at least use a plastic toe cage (or a clip adapter). They don't cost much and you don't need to be racing get a foot in the front wheel. Particularly with road bikes as the wheel aren't as stretched out as they are on [say] a cruiser [bicycle].
Whichever system is used to keep feet on the pedals its always a good idea to practice track-stands. I slip my left foot free when approaching a stop... but then still try to just balance till I can ride off without dismounting to place a foot on the ground. Feeling comfortable to pause without pedaling can be helpful when a distraction leaves you stopped.... and still clipped in.
