I hate to say it but you are never totally free from the possibility of falling while clipped in. I almost feel yesterday. I was at an intersection and was about to take off. I only had my right foot clipped in when I saw a car coming from the left. Went to put my left foot back down but the cleat stuck for just a moment to the pedal. It wasn't clipped in but just caught on the pedal. I almost went down. It was kind of funny because as soon as it caught and I started going down I was thinking to myself, "Man, I can't believe I'm gonna fall." Luckily it came out at the last moment. So I bet even those that have been riding for years go down every once in awhile. But at least not as often.
