I've only fallen twice and both were when I first started using them. The first time was during my first ride to get used to them; I stopped at a corner and by the time my mind figured out what needed to be done I was on the floor because I tried to move my right leg but forgot it was clipped in. The second time was at a busy intersection where I was trying to filter through stopped cars; I unclipped but didn't prepare and that's all it took. It's second nature now so I don't ever come even close to bailing now.
